The type of cams, longer axle to axle and the longer valley of they whitetail give you that smoother feeling. Or at least that lack of fighting you. The whitetails longer valley keeps you at the big let off over a longer draw length of the bow. With the Reflex you have a shorter valley, harsher cams and all that mumbo jumbo. If you creep just a little forward the bow wants to go off and it wants to yank you out of the valley and send the arrow down range. It's a product of the harsher cams designed for more speed and all that. With your Whitetail at 65% letoff the break over from full draw to release is not nearly as drastic as it is with your new bow. You want a little of both you should probably look at something like a Darton or something with the cam and a half modules, longer axle to axle etc etc.
