Ok i seem to see alot of differnt cam set ups on new bows. Some are single cam some are double and i know i few hoyt and reflexs are cam and a half
Which one should i want in a new hunting bow and why

well in my experience the dual cam bows have a harsher draw cycle but give you impressive speed. Single cam bows allow for smoother draw and speed but not as significant as dual cams..This isnt the case with some bows. Matthews gives you single cam smoothness with a fast IBO speed. And also a single cam bow it seems in my experience that I can draw and hold a single cam bow longer. So its all preference.

I'd take smooth and quiet over speed any day of the week.

so whats the deal with the cam and half bows

Its litterally a hybrid. You get improved speed by having both limbs work together... as in a two cam bow... however, you also get the smoother draw cycle and ease of care/lack of maintence that a single cam offers.

Honestly, they all have their ups and downs. You really just have to shoot a Mathews, a Hoyt and a BT and decide for yourself.

does anyone but hoyt have a cam and a half. seems like hoyt and reflex which is owned by hoyt are the only one.

watch out for a single-hard cam. They make a 60lb draw weight feel like a 70lb draw. I have felt this difference in person and it's definetly true. I read somewhere once that it's because they require more string, but idk how true that is...
