I fletch my own arrows with AAE stealths. I like the flexibility, lower clearance and low memory of the stealth. I put in a little helical and 4 fletch on my arrows in my bitzenberger. Don't have any plans on going back to blazers anytime soon. Just adjust the set screw to 90on the straight nob, you do not need any additional nobs.
I like 4 fletch for switching between broad heads and mechanical's depending on what state I'm hunting. Only difference is the broad heads drop just a bit more, left and right are exactly the same. For people who say field points and broadheads fly the same...maybe at 20, 40 highly questionable beyond 40 no way. I'll take the extra vane.
