Alpine climbing: hard shell or light rain pants

For ice and alpine I usually wear a heavier duty soft shell pant (OR Cirque). These are great in dry and cold conditions but I’ve never used them for an extended period of time during wet weather. They are usually pretty soaked after a pitch or two of dripping ice. This winter I will be doing some climbing in a place with bad weather and humidity. I am trying to decide what pant systems to use. I am between getting a dedicated hardshell alpine pant or a lighter weight pair of rain pants that I can throw over my soft shell pants when the weather gets bad. What is your experience with hardshell pants while alpine climbing?

Dedicated hardshell as a primary layer is your best bet, you're not going to be stopping to put on a light weight shell and by the time you do your soft shell trousers would probably already be soaked. Get some fairly high cut salopettes and some fleece salopettes if you can find them. 

I don’t anticipate walking through very much deep snow and I will be on a lot of rock/mixed terrain so bibs seem like overkill. A lot of the climbs I’d like to do have steep snow or mellow ice to get to the hopefully dry rock. I’m worried that a pair of dedicated hardshell pants will get destroyed by the rock and I think the only time I will encounter heavy rain or wet snow is on the approach so maybe keeping a light rain shell in the pack would be best 

I really like my outdoor research trailbreaker. They are hybrid hard shell soft shell with the knee down being hard shell. The only thing I like about them less than the cirques is that the cut is a little baggier. 

I got a pair of these curtsy of Pataguchis return warrant.....

An alpine workhorse built to thrive in cold, snowy conditions, the Triolet Pants feature a waterproof/breathable, 3-layer GORE-TEX shell fabric—now 100% recycled—in a full side-zip pant. Fair Trade Certified™ sewn.

THE BOMB.....For ice climbing I like a pant I can also use back country skiing so zips on he sides of the pants are great for venting while skinning or hiking in...
