The best selling point of the ISIS is that it weighs a few ounces less than the competitors----some say that is a big selling point but I find that weight suspended by the shoulder, to not be much of a factor.
I think the CounterCoil is a better unit, in every aspect, for alot less money. I think I know where a couple of used ISIS units are, or were if interested.
having shot most reducers, i think the isis is one of the best, especially if the arm is not fully on the shoulder. i have the unit made for premounted shooting and set for "heavy" 32 gram loads. it has dual return springs for rapid recovery and shooting the quick second shot in bunker does not catch the unit partially collapsed. it makes the ultra high speed bunker loads feel like smallbores! it is VERY light and well made.
it may be pricey, but what quality parts for tournament arms AREN'T?
