While I have had some success in lockpicking prior to joining this forum, my progression in skill is constantly hampered by my inability to grasp 'the proper hold' concept... that is, at least, when attempting mounted locks. I am fine with the proper hold of padlocks (which is what I tend to practice on most of the time).
Since I am right-handed, I find myself better able to feel/apply tension with my left hand and pick with my right. However, whenever I try picking mounted locks, I find myself in an awkward position trying to pick the same as I would a padlock. So I tend to use my right hand to apply tension and my left to pick.
The thing is, when I do this I can't properly feel what is going on inside the lock, which often results in me jiggling my pick around and hoping for the best (which is usually to no avail

Woould anyone be able to offer any advice on this problem?
Thanks a bunch
