I SHOOT A HOYT CYBERTECH AT 70 LBS, AND SHOOT MUZZY'S 4 BLADE 100 GRAINS AT 280 FPS, WHICH WILL HIT IN THE SAME PLACE AS MY FIELDPOINTS, ALSO 3 BLADE 100 GRAIN THUNDERHEADS WILL SHOOT JUST AS WELL OUT OF MY SETUP, WHICH IS HOYT CYBERTECH 30 INCH DRAW AT 70 POUNDS WITH GOLDTIP XT 5575 ARROWS, BUT IT IS ALL IN A WELL TUNED BOW, I PAPER TUNE MINE EVERY YEAR TO GET IT WELL TUNED, AND DON'T BELIEVE WHAT YOU HEAR ABOUT HAVING TO SHOOT A HELICAL FLETCH FOR GOOD BROADHEAD FLIGHT, CAUSE I HAVE SHOT FIXED BLADES FOR YEARS AND HAVE ONLY EVER USED A STRAIGHT FLETCH, HOPE THIS HELPS
GOOD LUCK.
