Rangeball, I've shot the 04 BowTechs. I bought a 70# Liberty because it is the first bow I could shoot without straining at 70# (back probs). I think the F cam will be easier to draw back slowly and smoothly when need be. There isn't that hump to pull through right before the valley. I was deciding between the Liberty and Patriot single. I was considering a 70# Liberty or 60# Pat. I think the Liberty at 70# will be as fast as a Pat at 60#, shooting the same 375 gr arrow. Maybe faster. I'm also interested in a Justice or Mighty Mite. I tried both of those in 70# and, the Justice was noticeably easier to draw. But the MM is noticeably faster. For my intended use of a short bow, I'm leaning toward a 60# Justice. But I'll wait until I shoot a 60# MM. Am I making any sense?
