Well if the wait time works out about the same with the Centaur spot, then it comes down to looks and shooting. That stuff is all most all subjective.
I wouldn't have a bow bolt without a fair amount of phenolic. That and the bolt will add some weight so being too light or mass weight in general should not be a big deal.
I had a Centaur for a while. Not crazy about the carbon look, but it is okay. I like nice veneers a lot better. I know you can get a Centaur with wood veneers, but that is not the hot Centaur most people want. Also the Centaur bows I have seen had a more textured finish. Looks like maybe it would be better for durability, but I like the finish on a whip better.
I have only shot a few whips, but liked the grip better no question about it.
Without shooting them side by side at same weight and arrow it is hard to compare speed and sound, but my best guess is the Centaur is faster and the whip is quieter.
I guess if you want me to pick one for you, it will be a whip for quiet, looks, and grip. Do you want weigth, length and wood combo also?
