Probably but more speed is a great thing to have if YOUR accuracy isn't sacrificed
For me, getting more speed is okay, but I always ask the question, "What did the manufacturer do to give me more speed?"
If they reduced the brace height, gave me more reflex, or made the draw force curve steeper, then I don't necessarily want it. If the reason was a more efficient design, leaving me with a bow that is as forgiving as I had in the past, then I'll take the speed without complaining in most cases.
However, there does come a point where too much speed will take away from archery (in my opinion). I used to like watching the flight of my arrow. I don't see the arrows so well today. I use to like the challenge of using a weapon where few could get close enough to make a kill. Today, it can be done at distances that approach what I'd take with my shotgun. I use to enjoy the practice that was required to become proficient. Today's beginner is a better shot within 2 weeks of steady shooting then an experienced archer of 30 years ago. The lines are starting to blur and it's becomming less and less of a primitive weapon and more of just an efficient weapon of choice. I know that this doesn't bother most, but for some reason it takes away from what I always felt archery hunting season was meant to be.
