You are right, Hardwater. The Ion Alphas had the turbo blades last year. The angle of the blades is a alot more aggressive compared to the Pistol Bit. The new E-40 auger looks very similar to the Ion, but with a few slight changes to the head. It also shed a couple of pounds with this new design as the Ion Alpha plus was 15.9 lbs. and the new Eskimo E-40 composite listed at 13.5 lbs.
