Fastest bow is Goldstrike Arch. A fast base speed plus the auto 50% IAS makes it the fastest without any doubt, and Buriza is extremely S L O W compared to Goldstrike, Best thing is that in duels, if you got 100% pierce (level 10 pierce plus Razortail) you can do more damage than Buriza. BTW, screw going for buying one of those bows. Damage and stuff is less than eagle, but can cost more for less damage and mods.
