Like: Baby Face's Blaster
(Sure you get slowed down but it does OK damage and I like the speed boost after getting a few hits in)
Hate: Darwin's Danger Shield
(Too many reasons, I have mine so I can have the Croc-o-Style kit but I hate others who use it so I never use the dang thing myself so I don't look like a complete hypocrite after I ask someone why they're using it in a generally non-amused tone)
