Well, after tearing up 3 of my 5 good arrows I bought some a dozen bare shaft SuperSlams. I am sticking with the alums for now based on my personal testing of them vs. carbons, which was fairly basic - shoot both a whole bunch of times and see which ones grouped/flew better. Kind of not on an even field, though, as I'm using a whisker biscuit for alums. I would guess the carbons would group better with a biscuit for carbons. I fletched 8 of them with 4" red hen feathers and a black cock feather, 2 of them with 4" orange hens and green cock, and 2 with 4" plastic vanes, all with a right helical. I fletched the 2 with plastic so I could compare them to the feathers. I haven't used feathers before and it seems the feathers are flying a tad faster than the plastic. About an inch or more higher at 20yds. Also, the plastic helicals seem to hit about that much higher compared to the straight plastic vanes. At least thats what my not-so-scientific testing has told me so far. The feathers seem to be holding up pretty well going through the biscuit.
