Approaches to LB's lead guitar parts

[cascade13]

This topic cuts across a couple Ledge boards, but I figure it's most relevant here nowadays. Any number of articles or comments talk about LB being replaced by two guitarists...twice. I'm curious about how someone with more musical expertise than me (meaning, any expertise at all) would describe Rick's, Dave's, and Mike's approach to LB's lead parts -- how much of their own styles they seem to incorporate, whether there's a notable difference in the guitars they use, how they work with the rhythm guitarists, etc. I'm not looking to say one is better than the other, mind you...just a better understanding of their technique/philosophy/influences. Thanks in advance!
