Voices might be my favorite JP solo ever, not just from this list. It has everything in it, kicks total ass, and works perfectly within the context of the song.
The solo at the end of Lie is definitely most awesome, too. Even though I don't care for Constant Motion, the main riff and JP's solo are both great.
Panic Attack and As I Am are both good, but not really notable when you consider how many solos he has that are better.
