Just bought a Grayling from Cabelas 30 bucks, chose right hand helical as I have a Boehning straight/offset (paid 60 bucks) both are very similar and (I tried this) you can swap clamps between the two with great results. Also I am using "Fast Fletch" adhesive for my fletching. It doesn't run (if you use the right amount) and sets up in seconds. So far in the short time I have been fletching my own arrows I have spent enough to buy quite a few dozen factory fletched arrows. BUT! I am having a ball learning and monitarily I think I'm catching up.
Now onto cedar shafts, cresting and feathers .... wish me luck.
