99 times out of 100 IF your bow is paper-tuned most Broadheads will fly well depending on spin test, fletching, and blade size.
It used to be people switched to mechanicals for better flight....now some of best flying heads are fixed heads.
Some standouts for accuracy I have tried are Wasp Drones, Slick Tricks and Muzzy Trocars.
I have shot all of them out of tuned bows out to 90 yards.....
