How close is Frederick to Baltimore? I'd suggest you go see Len Marsh at Macrotech Archery in Baltimore.
As for which model? Oh geez.........

Depends what you are hoping to do with it or what you want it to do.........you want super quiet recoil free and decent speed? You want a shorter ATA length or longer? You want it to be a dual purpose hunting 3D bow? etc etc?

All the models are so different that unless we have an idea what you want to do with it it's kinda tough to say anything other than ALL OF EM'

(I was wondering when you were gonna start asking questions. LOL Although brief it was good meeting you at the show.)
