Just to stick my nose into this thread. I think that meticulously building your arrows and aligning your broadheads is more important than what rest you use. Reason I say this is that I have used drop aways for 3 years now. My fixed blade broadheads always flew differently than my fieldpoints no matter how much tuning I did. Therefore, I used mechanicals and got good groups out to 35 yards. Well, after talking to Len, who says that any broadhead should group with your fieldpoints out of a properly tuned setup, I decided to pay more attention to my arrows. I went so far as to float them to find the heavy side of the spine. I reamed the ends so that they were at a 90 degree angle to the shaft before installing inserts and bushings. I reamed the inserts and bushings before installing broadheads and nocks and then spin tested every one of them. I also weighed them and they are within 0.5 grains of one another. After doing all of this I went out and shot the arrows with broadheads attached. Guess what, they all grouped with my fieldpoints. I can shoot a broadhead tipped arrow and then a fieldpoint tipped arrow at 30 yards and they are within 2" of other. If I was a better shot, they might touch.

I am using Carbon Express CX200's cut to 27" long. Aluminum inserts, Easton Uni Bushings and G-Nocks. EZE-Crest wraps and 3 Blazer 2" vanes. I use 100 grain fieldtips or broadheads. My fixed blade broadheads have 4, cut-on-contact blades with a 1" cutting diameter so no, they aren't Slick Tricks. Total arrow weight is 352 grains each. One of them is 352.5 grains. They are traveling at 298 FPS out of my Bowtech Defender VFT using a QAD Ultra Rest. So, you can get a fixed blade broadhead to fly well out of a fast bow if everything is built and tuned properly. Now my only problem is my consistancy.

This is not to say that you don't have to tune your bow properly. I just feel that you need to have your arrows right before you try to tune with them. It made things a lot easier.
