Nice to hear your opinions guys-still very early days for me, but at the moment the standout ones are the Ultex Sharp and the Hetfield Black Fang-however the Petrucci is currently my front runner; its fantastic-very very accurate and clear on solos, best soloing pick i have tried-hands down, it actually made me play cleaner and better from the off!. What I am trying to see is if i can get used to it enough to play rhythms with the same intensity and accuracy i am used to. So for a pick to work for me, it has to work for a variety of metal rhythm styles-tremolo picking, triplets, 16ths, 32nds, etc.
At the moment i just cant get used to the normal Jazz III picks im afraid, they are so tiny, maybe i should try the bigger ones-i believe the Petrucci pick lies in between these 2 in size.
Will give them all some more spins in the next days/weeks/months-its incredible when listening through headphones how a simple pick can alter the sound, brightness, and clarity of the notes. But as with anything it has to feel right for you and the only way is to see how it makes you play.
