Tension 20, 30, or 40?

The daily Tension Board post.... and yes, I know there are no holds available anytime soon :)

What angle do you recommend for a tension board?  Will be used by me (the old dude who still prefers slab) and my son (the young gun).  My gut says split the difference and go 30 degrees.  Height is not a problem.

Anyone?

Make it pivot!

The old dude or the young gun? :)  Realistic range is V3-V8....

I enjoy 30° more than 40°, more specific to harder climbing in Oregon. Still be plenty hard with any hold set especially the screw ons.

Is 35 an option? I would do 35 or 40.

You gotta do adjustable, unless you already have a lot of other climbing space. The added expense compared to the rest of the project would be pretty minimal, and the advantages are huge.
I've spent a lot of time on a 40 degree, only a little time on an adjustable; however, it seems like the difference between 40 and 20 is HUGE.

So, let's say for the sake of argument that you can set it 10, 20, 30 and 40. That's a lot like having 4 different walls. You quadruple your climbing space.

For me, at my level, I would use 10 to warm up and ARC; 20 to work the smallest, fingery holds; at 40 I'm mostly limited to jugs; 30 would be a mix. You can also work projects by reducing the overhang ... and of course you and your son seem to be at different levels, so it makes perfect sense.

I put mine at 30.  I prefer vertical to slightly overhanging technical routes, and this seems to be a good angle to train for my goals.  The majority of the holds are quite positive, so both of you may outgrow 20 quickly.  For me, there are only two holds (the small roundover and the big 6" sloper) that are difficult to grab at 30.  I don't climb at a high level.  If you decide to go with the tension board, Id recommend getting all 3 sets of holds and the LED setup. 

I would echo getting the LED lights.  It really helps to sort out problems, as many of the holds are quite similar looking.  I made mine somewhat adjustable using two tongue jacks (look up my pictures in the “what does your woodie look like” thread or I could PM you some pictures, it was fairly straightforward and only added about $100 to the cost of the whole thing).  It can go from 35 to 45 degrees.  I like 35 the best because I can use a lot of the less good holds.  I also have liked being able to progress on problems by doing the same problem at a steeper angle.  I project V8 on the board.  

If adjustable is an option I'd go that way for sure, I have chains supporting both corners and a small winch to adjust the angle, takes 2 minutes to change it and I feel like it's a much more useful tool that way, I boulder in the V8-9 range and if you have the full hold set there's plenty of holds that are pretty hard to use at all at my level at 40 degrees,  it feels like you want the steep, big holds for building power and tension, but  20 degrees opens up a lot of problems on the small holds that work an entirely different skillset...
