It all depends......typically longer is smoother and will draw smoother at a longer draw length.......but, there are exceptions. The Bear Montana is a bit of a club compared to a nice R/D longbow. Unless your are really hung up on a Hill style longbow I would suggest a quality R/D longbow. Toelke Whip is a great place to start. The are easier to shoot, cut to center, faster, much less hand shock and just a more pleasant shooting experience. As always try as many and possible and shoot what fits you and your style the best.
