Never really seen this one brought up before.
Please link it if there is another thread about this.
I feel like a standard rock TR setup would work pretty well (you always have the backup knots if the main device fails.)
However, most people just seem to free solo instead of rigging ropes.
Who's done it?
Seems like to Silent Partner would be the most iced up rope proof(ish.)

I've seen it done in the ouray ice park but didn't look closely enough to see their specific setup.

If you actually fall on a solo belaying system on ice you'll really be wishing for a partner to get your broken body to the hospital. good luck self rescuing with two broken ankles. If you're gonna solo do it on something well within your abilities and enjoy moving without the bother of a rope.

Roped solo TR is no big deal using any of the usual setups. Just keep the device dry (i.e. no slush on the rope). If you periodically clip into a second rope as a backup, this can result in a bight of rope below your feet, which Murphy's Law says WILL snag on an icicle at the worst possible moment. BTDT.

The rope soloing is pretty straight forward. Fix a line and use an ushba or a gri. I've used both for years without problem.

I was kind of leaving it open to see how or if people do either TR or leading.
For my uses I am looking to TR.

Good advice Mike, didn't think about the loops snagging. Might be best to go Petzl style and use two devices instead of knots.

"I've logged over a few hundred pitches on my TR setup with no worries, great way to get pumped and run laps without having to bring a partner along."
What's you setup Bud? Any tips?

I've done it on the soloist, easy setup and great to get in a bunch of routes quickly...same as for rock obviously

The silent partner is not recommended for use in freezing conditions or with icy ropes. Frozen water inside the clutch can prevent it from locking and ice on the rope can interfere with the clove hitch cinching down properly.

I was referring to roped solo leading. Yeah, TR soloing on ice is super chill, I'll shut up now.

I favor toothed devices over camming devices for icy ropes, but I am just speculating.

I've used a petzl ascension countless times in easy routes. Just backed it up with another petzl traxion. Never has let me down thus far. But I've never fallen because I only use it up to wi4.

Good info everyone. Very good point about the SP clutch freezing.
I'm thinking Minitrax backed up with a GriGri.
I have never been a fan of rope soloing with toothed devices, but with ice I don't plan on taking multiple (if any) falls.
As far as just using one device with no backup, that is a no-go in my book. I know a lot of people are cool with it but backup knots have saved my ass twice.

I use a micro traxion off my belay loop and girth hitch a 12" sling through my harness with a tibloc on the end to trail behind. I would use something else to back it up if I had it. I typically coil the rope so that it is hanging just off the ground, but I see some folks put an ice screw in at the bottom and clip to it. I just rap with a gri gri and get pitches in until my rope ices up.

mini traction,spinner leashes,substitute backup knots for freedom to climb.

Ive done it with 2 lines. 1 with knots clipped into harness as backup and 1 with a jumar and weight at the bottom. when the rope ices up this setup becomes kinda scary.

It's a great way to log a lot of vertical mileage without freezing or boring your partner. No better way for training, IMO. (I refer to TR solo, not lead solo)

I anchor the rope in the middle, and drop both sides of the rope. Clip a mini-traxion to one strand and an ascender to the other strand. Has worked great for me, runs smoothly.

I just got a petzl shunt, which I plan to use instead of the ascender.

I use the same system I use for autobelaying on rock: fix both strands to a top-rope anchor (e.g. using a fig 8 on a bight), clip an USHBA to my belay loop on one strand, and clip a Petzl Microcender to the second strand, as a backup (per Petzl's recommendation "Installation on the harness with two ascenders" at www.petzl.com/en/outdoor/self-belay-solo-climbing/solution1->>> ). I weight the ropes with my pack and am ready to climb.

I was fortunate to find one of the last available USHBA devices before they were discontinued; it supposedly works well on muddy and even icy ropes, and I like using ascending devices without teeth.

It does take a minute to switch to an ATC Guide for rappelling; also I carry a foot Prusik cord in case I get stuck half way up (which happened on Monday when the ice I was hoping to climb was already full, so I tried a challenging mixed route nearby -- damn, you can get pumped out fast when drytooling!).

I tr solo with a gri-gri on a single fixed strand. I tie back up knots every now and then. I don't clip my knots, but figure they'll act as stoppers if my gri gri were to fail. I've never had trouble with it not gripping on the rope though, even on my 9.1mm dry treated rope.

I would prefer a system that self feeds, like an ascender or mini trax, but I don't tr solo enough to buy dedicated gear, and I'd rather not tr solo on my ascenders.

I use minitraxion on a single strand with long sling around my shoulders to keep the device up. I've used it a lot for both rock and ice and have never had an issue.
You do need to do a few things though like file off the lock back tab so it doesn't open and stay open. It is also recommended that you use a steel locking carabiner to your belay loop. And in previous posts someone mentioned backing it up with a grigri which does not work because the device no longer feeds. If you're worried about one device run two minitraxions in sequence or an ascender as others have said.

The mini traxon is the way to go on a icy rope. I have used this with a fixed line and a back pack to weight the other end but still pull it up if i want. I place my traxon at my waist some times with a screamer and just push it up with my knee when i move.

Regarding the mini traxion, this is from Petzl's Website.

Use of the MINI TRAXION pulley:
Warning!
Petzl has studied the current usage of the MINI TRAXION as a self-belay device on a fixed rope. Serious accidents and many handling errors have been reported.

The risk of using the device with the cam held open is significant, as well as the possibility of accidental opening of the cam when climbing.

Consequently, the MINI TRAXION must be paired with a different ascender: ASCENSION, BASIC, MICROCENDER...
Petzl does not recommend using a system consisting of only two MINI TRAXION for selfbelayed solo climbing with a fixed rope.
