have been even more suprised at the lack of trajectory difference between shooting 300 fps and 280 fps !
I think alot of people would be if they took the time to look at the trajectory for any given arrow. I remember reading some time ago that there was a somewhat significant difference between 220 and 280 but once you get over that then the next "significant change" was not until around 330 fps. Maybe Arthur or one of you guys has the stats to back up or refute this but it sounded reasonable based on the facts at the time.
Finding a "middle ground" is what I have always suggested. Getting a reasonably flat trajectory coupled with good KE/momentum figures out of a quiet and accurate bow is something we should all try to achieve.
