Well, W2D, EDS, and D are all just stamina parts. The only bottoms that can really be called defense tips, are CS, RS, RSF, RDF, and RB. Anything else will be easily KOed by the current attack types in the metagame (That is, if the person launching them is a decent player with attack types). I think your combo would be more of a spin-stealer anyway, so I think you should use WD. It won't have very much defense at all, so it wouldn't be my first choice against an attack type, but it should OS quite a few things by spin-steal.
(if you want a good defense type, post all your parts in the build me a combo thread and ask for one. The guys in there will get you a combo asap
)
