WHEN we will see a 400 FPS bow? not sure- but no doubt the current crop of extreme speed bows are very shootable considering. Monsters have been selling extremely well, and no complaints about shootability. Most of these guys are not topping them out, but using a hunting setup shooting in the 320s-330s.
Draw cycles are the real issue now-cams like the AVS, Omen cams and some others appeal to a very, very small minority of consumers (and always do). Those cams are for the hardcore of the hardcore. Most guys who walk into a shop could care less- and if they did care, as soon as they draw one, they don't
The vast majority are just looking for a solid, accurate, easy drawing and shooting bow that will kill deer @ 20-30 yards. You don't need 330 FPS or extreme cams to do that.Speed is a added side benefit if they get it.
IMO- the industry will repeat itself like it does every 10 years or so- this current speed bow craze will taper off in the next year or two, and we will start to see some softer cams, and higher brace heights while still getting good speeds. In the mid 1990s, the cams were not really all that bad on most of the extreme speed bows- The Martin Fury Cams, HCA Hatchets, and PSE Maxis cams are much nicer drawing than todays counterparts- the real issue then was the super short brace heights coupled with relatively short risers, long limbs 45 degree limb angles and no string suppression devices to curb string oscillation- all that made for a REALLY tough shooting bow. They were the muscle cars of the day- great power, poor handling. we have come a LONG way since that time. These days a 6" brace height Katera,Martin Warthog, or 82nd AB shoots circles around those old bows, not just with the ease of shooting, but they do it with scads less noise, vibration,and recoil.
