Not really gimp, sorry
Is difficult (for me ear) to find two or more good guitars, usually one of the is always "backing". Glenn and KK are a perfect team, they read their minds, no one else can be there, not even Randy. If I add a second guitar to Randy, or Iommi or Blackmore or Page, .. I go for Steve Morse because he is specially good to "coordinate" his guitar with a keyboard (Which i hate) with Deep Purple, a violin with Kansas, he played Ozzy's songs in a very nice way, he plays classical, etc..
I don't like Phil Collins at least not with such guitars, vocals and bass, I'll go for a stronger one, maybe Simon Wright (of course I like Bonham, Cozy and Scott much more than him) and Ozzy needs no backing vocals
