DaveC brings up a good point Individual archers drawing the same bow will come away with sometimes much different opinions of "how it feels". I too have been having problems with my shoulders lately and the older I get, the more I pay attention to "how it feels". That's why I ordered a 60 pound Allegiance this year. My neighbor,,, who is a brute of a guy, thinks it's "too easy"[&:] I think it's "just right".
It's great that BowTech offers all the different cam systems for different people. My wife has the '04 Patriot and to her, it draws much better than her '02 Tec 29. They have improved the Infinity cam to almost perfection IMO as far as speed AND comfort,, plus, it's very quiet.
