Obviously the issue is NOT the b-head as the Slick Trick is known throughout the industry as one of THE best flying b-head you could find. As some have mentioned, you MUST tune your rig. If you don't know how to do this then you must seek out the help of your nearest Pro Shop.
Once you get your rig flawlessly tuned, you'll be able to shoot ANY b-head you want to the same point of impact as your fieldpoints.
Also, as some have mentioned..... I don't think a large cutting mech b-head like the Rage would be the best choice for your lower poundage equipment and your lack of experience. Shoot a fixed blade and go for maximum penetration. I think you'll be more pleased with the results.
Good luck this season
