Love dye, mostly for the matrix, although i loved that before dye got their hands on it.
But barrels... meh. They're good for sure, but i'd never buy one separately. Proto barrels are just as good. Heck, CP barrels are just as good. And if you were already thinking DeadlyWind, just get the Fibur (uses freak inserts, which i recommend you purchase separate from the Fibur itself, cuz you can find the inserts cheaper).
