I've currently got my mind set on ordering one of these beauties. I'm a one piece guy and was curious what is the diff between a PA and a KB? I'm currently leaning towards a PA. Also, I'm not a speed freak guy but I like flat trajectory do these bows accomplish that? I'm looking for a all around bow that I can shoot for hours at a time and not tire. My current hunting bow is 72# but after a dozen shots or so my accuracy starts to suffer, so I'm thinking of getting something in the 58-62# range. Thanks
