I've written more than a few times that this is exactly how I utlized my two different mods... I keep my bows at 65, and used the speed mods all the way up until the temps dropped below freezing this hunting season. Once it did so, I switched to the smooth mods with no noticeable difference in POI at hunting distances, and I could draw just as easily in the cold temps as I could previously when the temps were higher.
Greg/Mo, dispell a rumor for me. I've heard that bows should be set at their max. draw weight for their optimum performance. Is there a real deficit in setting them back?
