I took my bull this past season with bow and despite what the Archery Hut told me about my PSE bow being junk and arrows that they said needed to be heavier that bull damn sure seemed to drop.

In in my experience if that weight of arrow is comfortable for you to shoot then stick with that. I have seen more guys mess up perfect shots because they change one little thing. If you have put that many arrows down range on that bow then stick with what you have.

Also try to find someone to help with your bow that doesn't care if you shoot PSE, Hoyt, Matthews, or any other brand they will give you the most honest opinion. To many so called pro shops just want you to buy their crap and are name whores.
