It kinda did. As I started w/ trials not so long ago, I didn't know whether to have my finger on the front brake or not so I just didn't put it there. Then I saw people having their fingers on the FB and adjusted accordingly. It certainly felt less powerful back then. Now, whenever I try to grab the bar with all my fingers, it feels weird and less powerful. I guess it has to do w/ conditioning and the brain and what feels comfortable meaning: comfort = power.
p.s.: I also have to push the "I can't sidehop for shit" button but then again, I would need a button for "I can't do anything really".
