WidowEater,
I'm working up a set of footed hex shafts that I got from Bob Burton at Whispering Wind Arrows a couple years ago. I'll let you know how they do. As to your original questions, I bought them because I was looking for a heavier arrow for Africa - they are heavier than POCs, and I have a hard time getting hardwood shafts in my spine (90-94#). The ones I got from Bob should finsish out at 775 gr with a 125 gr BH; my equivalent tapered POCs max out about 620 gr. Because of their composite design, nock alignment (to grain) is not an issue, which is nice, 'cause after the end is painted and sealed, it's hard to see the grain at the nock end of a POC shaft when installing the nock. Mine are quite straight and have stayed that way (unsealed), and those that had a slight bend in them were easily straightened with some heat from a heat (paint) gun, as per Bob's instructions. They also have a nice grain pattern that shows through the finish, and the footed ones are sure purty!
