RE: Marquis vs Black Ice
Landon, I wouldn't get caught in the speed/KE numbers game. There are a lot of things I look for in a bow besides speed. KE on most bows are more than ample. Also trying to shoot one pin out to x-number of yards is not that important. I still have some speed bows No doubt, but it seems every year I go to a little heavier arrow. The Black Ice and Marquis are both very nice bows. I myself would prefer the Marquis if I could choose only one. I wouldn't overlook the Allegiance, 101, Guardian or 82 either.
I wish we were closer you would be more than welcome to put all my bows through their paces.
Good Luck in your search!!
