Amen bowfanatic. I was wondering the same. At those speeds, if a fixed broadhead is used. I don't think that most could shoot them without some type of plaining problem. If a flat shooting bow is what you want, let me save you some time. I shoot ALOT of 3-D and thought that I needed 300 fps or higher to remain competitive. I did a test switching from 423 grain arrows to 350 grain arrows. I broke the 300 fps barrier and my groups opened up slightly. Using my sight settings my 20 yard group raised. I was pleased thinking that I would shoot flatter. I adjusted my sight for 20 to hit right on. To my amazement. All of the pins were hitting right on. I was astonished that up to 50 yards there was no noticeable change in point of impact to 50 yards from 285 fps to 300 fps. The only difference was that the lighter arrows traveling faster speeds were not as pinpoint accurate. I opted for the heavier set-up and went on to take a state title
last year along with a turkey and a bull elk. I just got my new bow for this year and opted for a longer brace heighth(8.25 in.) and am using 405 grain arrow. This is proving to be more accuate yet as my indoor 3-D and NFAA scores have come up since I have changed set-ups. Accuracy is the name of the game. I would much rather have a slow arow in the boiler room than a fast arrow in the shoulder blade. The new bow is shooting 283 fps. just right for me.............
