Very underrated indeed. I'll be the first to admit there is some filler on Mane Attraction and Big Game, but Fight To Survive and Pride are pretty awesome. Pride was pretty sappy in a couple of places, but few bands had a groove like they did at the time. Vito was certainly a GOD, but James and Greg were actually pretty darned solid musicians as well. James was pretty busy trying to be prettier than Mike, but Greg actually played for Anthrax before joining WL.
What separated WL from pretty much other bands I heard at the time (not just the "hair" metal variety) was how Mike and Vito fed off of each other. There are not any examples I can think of a singer and guitarist that accent each other so well. It also helped that Mike could freaking sing his ass off live as well.
