Although i am no expert on the subject by any means, olympic lifting is the way to go. I have challenged many of my friends who talk about verticals to do cleans a cuople times a week for like a month and come back and talk to me. And sure enough, nearly everytime, they put on 3" or so to their vertical leap.
Having run into Steven on a couple different sites now, i believe you would not be doing something detrimental to your training by following these guidelines. Especially cause i have not experienced any training that gives as much improvement as the oly lifts do. My favorite is the power clean, but that is just me;-)
good job Steve
