i own both. if you loved your centaur, then i suggest you get another one in dark matter. my 58" dark matter with a low grip weighs 26.2 oz with all the weight in your hand, light limbs because of the carbon. superb bow..
my whip is 64" all phenolic riser and comes in about 23oz. add a bowbolt, and it would probably be 25-26 oz. this bow is glass limbs and all that dan offers.
in my opinion the whip is quieter, probably due to the bamboo core, but i like the way the centaur draws better.
honestly both are nice bows and you will probably have to try a whip to decide for youself, but for me the centaur in dark matter wins over the whip..
