For me, yes. The 650 grain arrow at 200 fps or so is better, because that is what I like. A 425 grain arrow at 270 fps is fine and I know it will do the job on most anything in North America, as will mine. But I guarantee if I had the chance to vote on making a 400 grain minimum arrow weight for hunting, I' d be checking the YES box. Yes, even for light draw weight bows. Arrow mass comes into play for light draw bows because they lack energy.

Some well seasoned shooters are capable of tuning and controlling broadheads with those sub-400 grain toothpicks out of high poundage rigs and are capable of using them in the woods. From what I' ve seen over the past 6-7 years of conducting proficiency tests for a local WMA, the guys that can handle that speed would number less than one in 500, maybe less than one in a thousand. What expert shooters ' need' and what the average shooter can get away with are way different things. The below average shooter would be a danger to everyone and everything in the woods with a 345 fps setup!

Like I said before, speed is fine as long as you can control it. But there are far more people who would be far better off shooting 250 fps and under than there are that can shoot 300 fps and over.
