Their rapidfire is nice, but it would be better to choose which ones to shoot at. Plus, it takes a lot of arrows.

I didn't find them to be too strong, even with the right arrows, my regular fighters were better.

I was going to switch to them, but found out that the strongest bow I have is 70 strength. And the arrows can be anywhere from 20-30. So thats like 100 right? any one of the other weapons I have equipped right now has more strength than that. Plus, dual weilding makes it double.
