Wood is a hack of Gen I, not II. And there is a big difference between those two.Voting for Super Rising Thunder as it is easily the best one up there.
Edit: Also I just thought I'd point out, some people (not me, but some people) find hacking Gen III harder than hacking Gen II, so it isn't doesn't take any more effort than a Gen III hack at all :P
Anyways, I like both - Super Rising Thunder and Wood but Sawakita's assembly work is just fantastic so I vote for Wood.
