Yeah, I'd figure that Rachel would better fit a longbow; it's just that I remember Wood saying that he'll give Betsy more weapons. Though, Rachel and Betsy both using weapons is just as good! As for Psylocke being the first to use psychic weaponry-- I think this is a true statement. I know that Julia Carpenter also had psionic-based webs; however, I doubt that was before Betsy. Jean and Rachel always used their power in a raw fashion. Charlies Xavier...? I'm not sure; I just know that there is a LOT of history before Psylocke's introduction. Xavier or Jean could have very well used psionic weaponry before, but probably just as a one-time thing.
