I have one of Ricks bows. Just got it back in the start of Oct. I have the stringer in 58". I tried all 3 sizes and really couldn't tell a huge difference but there is a difference. I really could make up my mind so I went with the 58 because it was in the middle. You can't go wrong with any of them IMO.
I did go with the upgrade of action bamboo and was really glad I did,,,man I LOVE the way it shoots. After I got it and got it set up I was shooting great out to 20 yards within 1 week.
I was a compound shooter before I got this bow(I started out shooting recurve as a kid)but found myself taking both bows every time I went hunting this year and seem to pull the stringer out more than the compound.
I got so use to this bow so fast that I impressed myself.
I would suggest you think about how you will be hunting with this bow, treestand, blinds or just ground hunting. If you are going with treestands and ground blinds I would go with one of the shorter ones but thats not "mandatory". You can still do all the styles of hunting with the 60".
