I have a slight preference towards the Dye barrel although I agree that the Deadlywind is more bang for your buck.
There is more discussion about the CF boomy with some weights posted (images are poof gone) here: http://www.pbnation.com/showthread.php?t=3230817
I don't know tho if Dye has changed the CF Boomy since 2010?
Seems that if there were a 15" Fibur w/0.689 insert (we typically only make even lengths, but will do custom lengths), it would weight 80 grams so yeah a 15" CF Boomy 688" is.. 26 grams from being double the weight of a 15" Fibur.
OK enough numbers for now, let's go play some paintball.
