I've been into locksport for the past year, since coworkers came back from DefCon armed with all kinds of picksport goodies.

I find that I've developed a silverback gorilla approach to picking, though; I use so much pressure with the pick that I actually bend flimsy picks and end up with a sore thumb. While this approach has succeeded for any number of Master locks, several Chateau locks, several filing cabinet locks, numerous practice locks and even the Abus 55/40....it's limiting. I do not have the sensitivity I need.
Now, I am trying for a lighter tension, and holding the pick appropriately (as opposed to like a knife) and I find the success rate here to be nearly nil. What's the best way to re-learn correct picking technique?
Thanks!
