I am just back to target shooting after a twenty year hiatus. My 35 year old PSE Laser Flite, with the laminated wood limbs, is probably not safe to shoot anymore (anyone have an extra set of limbs?). My about 12 year old PSE Mach 9 is my current target bow. I am studying the new(er) PSE target bows. What is the practical difference between the PSE Phenom series, the Supra series, and the Dominator series bows? There is a price difference between each, so there must be some realistic practical difference, right?? What does one gain by shooting a pricier PSE target bow??? Thank you for your help making me smarter on this question.
