Phil shreds the guitar on youtube videos, but honestly, he never fit into the music Jovi, even his live work is vulgar, not remarkable. Phil could be well used if Bon Jovi wants to go for heavy riff songs, then that would be interesting.

I agree that John Shanks is a better guitarist for Bon Jovi, he has the sensibility these songs need. Also, he's a good guitarist (on a creative level), although he's not Richie unfortunately.
