This is an incredibly tough decision...... from all of Mike Romeo's and Mike Pinella's insane solos to Russell Allen's solo in Wicked to Jason Rullo's Death of Balance solo (I know they haven't played Death of Balance at some venues but he kinda does a solo at the end of Church of the Machine) to Mike Lepond's solo in Egypt (haha, I know they haven't played this at all venues either). I'm gonna go with a tie between Mike Romeo and Russell Allen because I was really impressed with his improv voice soloing in Wicked. I would've chose Mike Romeo outright, but I didn't really like his changes to the Sea of Lies solo and the change to the 2nd half of Of Sins and Shadows solo (on Divine Wings that lick is awesome, why did he change it???????!!!!!!).
