I shoot the ACC 128's but use a 4 inch helical vane. I switrched to ACC's a number of years ago and think in the long run it has saved me money. I very rarly have to throw away an arrow, they seem much tuffer than aluminum. This is of course just my perception but I have used the same arrow to shoot several deer. I have several friend who also switched and agree that they seem better off in the long run with ACC's.
