I started (as maybe most due) using thin picks--- the older I get the more I like a thicker one-- I bought the Petrucci to try ....and they sat in a jar with many other versions of picks I have collected over the years---I was using a Fender medium perloid green one for like 2 years--- and I LOST IT

I JUST had it wore in right-- it was PERFECT -- so I got out the container of picks and started the painful process of picking one at a time and using it for a little while and switching out of a whole ceramic desert cup full of PICKS the JP was the winner and been using it ever since
