Honestly, the Rage may just not be for you in this case. If you are worried about the KE, then you could just stick with your muzzys or another fixed head, Slick Trick is my suggestion, and be all set. For me, bowhunting has a ton to do with confidence, and if you have ANY doubt in your setup, it is going to affect your results. Without upgrading your bow, and your draw length, I think you have maxed out your bow as far as KE goes becasue like you have done, an increase in weight is really going to drop your speed. I am lucky in a sense with a 32" draw, my arrows are inherently heavy just based on length alone.
