Jeff, A lot of good points have been made here. The broadside issue is one and the heavier arrow is another. Dukemichaels uses aluminum and almost always gets pass throughs. I went to a Slick trick this year at 125g. Didn't get a pass through as the shot was seriously quartering away and entered the hind and guts (sorry). Animal is recovered and mostly gone by now.(I really need another deer) Anyways, I'm considering going back to aluminums for hunting. I just hate the durability issues. I bent a lot my first two years. In retrospect Jeff, you've gotten a lot of deer and everything seems to be working except for the Pass throughs. If it's that important go heavy, try Slick tricks and wait for broadside shots. If not you still are getting a ton of success. My hats off to you! Really. But I know the perfectionist in you will get you where you want to be.
