In reply to Ben_Megson: I've paid for the services of a sports psychologist in the past and for many people would recommend others to do so. I was competing in running at that time, but can easily see a lot of applications for climbing, particularly in how to achieve high performance states in stressful situations. I know Ueli Steck has extensivey used these services.
The survey is fine BUT you have two problems - a lot of people don't see the point (see Donny above) though I bet a very high % of climbers would benefit. Also, it then makes estimating how much people would pay difficult.
I enjoyed it and found it very useful so good luck
