I think ACC's represent an "era". They were the best and still are considered great; but there is definately better, from almost every vendor.
I loved the hyperspeeds. Hard to fin SOB's are still fun to shoot. Worst experiment ever was with ACC's. I tried to shoot 3-28's out of a 63# setup. It was like shooting a shotgun pattern. It was a tad outside of the chart recommendation (haha). But my calculations showed it should work. Good thing I don't build bridges
