There are a lot of fixed blade broadheads that impact where field points will. However, even the best flying broadhead out there will not fly true if your bow is not tuned properly and your arrows are not leaving your bow straight.
Some great broadheads have come to the market in the past few years.
Slick tricks, montecs, stingers, RM turbo and ironhead, Wasp Boss, NAP nitron, innerlock, razor caps, silver flame. All of these can be found by going to
Bowjackson's web site and visiting the different manufacturers sites.
Personally, I bought some slick tricks after last season and have not seen a better flying boradhead. I have not tried all of the ones listed abouve but I have tried a good number of broadheads and so far these fly the best for me.
