driftrider-i don't have one (yet) but i've been asking around this board about them for a week or two. Definately get the newer ones (have black and brown whiskers) and wear on vanes is minimal. Alot of guys shoot feathers through them without trouble. some think the biscuit-helical is a great combo. some thought, will say you ha ve tokeep the angle real mild.
use the search feature on this board and you'll find a half hour or so of reading on how people are liking theres and what seems to work for them.
