I have shot Blazers for a few years, getting pretty good results. Last year, I tried the Quickspin ST hunters. I think they work a little better, but individual groups/days, etc. are pretty hard to compare and judge. I would compare the STs with an offset to Blazers with a full helical. I decided to try an experiment with STs vs. FOBs. Shot some this week, and so far, the STs are doing as well or better. They are putting my broadheads with field points out to 40 yards, and I don't bother shooting much farther. I don't use a peep, since it causes problems in low light for my older eyes. Groups with STs have been under 2" at 20, 3" at 30, etc. The FOB arrows seem to shoot low for some reason. I am not getting contact, I checked for that. Maybe I'm pressing against the FOB with my face or something. Pretty hard to do a test like this without a Hooter Shooter or at least some Pro-like shooting skills.
