IMO if a Pokemon's competitive lifestyle revolved around Rapid Spin, then there's not much to look at.
Sorry if I offended anyone there, but that's just how I roll when I compare.
Feraligatr on the other hand is looking quite good. Having used a Sheer Force Nidoking before, I can understand how the added power brought to the table by that ability can help. Boosting moves like Waterfall, Ice Punch, Crunch, and Rock Slide can really help in a Dragon Dance moveset.
