For those of you that are good enough, congratulations. Us mere mortals stand in awe of your prowess.
Sometimes Arthur..your sense of humor really gets me going....

. You should be the last person trying to throw yourself in with " mere mortals" with your 7 foot frame and gargantuan arms.....
I cannot argue with the suggestion that a majority of the bowhunters out there are seasonal shooters at best but your comments bring something else to mind. With the relatively consistant increases in speed over the years that speed range that you are quoting as " too fast" might eventually be considered " slow" by comparison to what could potentially be obtained with new designs in limbs, strings, cams, etc.... Then a person will be able to shoot a 600 grain arrow at 270 fps and get the best of both of our worlds. What would you say to them then? Is 270 fps still too fast if there is a heavy arrow to back it up?
Finally,
I' ll make a deal with whoever thinks everyone needs speed. I' ll shoot your high speed bow if you' ll take a 10 mile hike wearing my size 15 AA boots. Then we can sit back and discuss how certain things fit certain people and not fit others at all.
I think I almost fit your criteria in terms of speed and shoe size. I will take you up on that....
Krisken,
Even though my own favorite hunting weight arrows fall close to that 400 grain mark I cannot honestly say that they will work for every setup out there. Sure the 400 grain minimum might help with those folks who are shooting arrows that are not generating enough KE or momentum but, on the other hand saying that a 400 grain arrow is the heaviest that one should shoot really puts too much emphasis on the trajectory differences for the various arrow weights that are currently used.
