Wow that was helpful. It's like having a personal trainer. Thanks so much. ericm979, To kind of explain myself about why I want to experiment with engaging other muscles; I think you're right, I don't think using other muscles will make me a faster climber. But I am kind of hoping that if I don't put 100% of my work into just one muscle I might be able to share some of the work load and possible last longer.

I had guessed that moving the saddle back slightly might increase reliance on the gluts. It's a shame my brooks seems to be about as far back as it can go. Those b17s have a short rail. Thanks for the warning on big gears. Since my knee has attitude I should probably be careful.

Carbonfiberboy thanks for all the tips. It makes sense that I should work on pedal form and efficiency in general. If for nothing else it may lessen the chance of my ACL acting up. I'm certainly going to work on it and thanks for the detailed drills.
