There are a couple of threads on here you can search, that may give some useful info. I recently bought an older, 60" model in 45#, that I am really just now getting to shoot a fair amount, and I am really liking it. Not my quietest bow, but I'm finally getting it settled down. And it seems to like stiffer arrows than I expected, as well as heavier, and it handles a range of arrows equally well out to 22 yds so far. If you like yours as much as I like mine, you will be quite pleased! Happy shooting!
