A combination of speed and emotion are my thing. Playn fast get pretty boring pretty fast as well as playn´ slow and it´s like, nothing happends. But combine them two and walla, you got a solo to satisfy both shredders and others.

I like Zakk Wylde´s stuff and Petruccis (just to mention few). Those guy can really mix things. Slash is great too but he´s not much into shredding. That´s a minus. Yngwie is great too but he´s too much into shredding (but he can play blues/emotional stuff better than most) but seems afraid to do it.
