Once you go hydro, its hard to go back. That would be a fun review, i look forward to it. You may be a little surprised though, those simplicity signature pros are solid machines. They have had the square tubular handles for decades, just what ariens went to on the pro series. They are built well and perform well. Better than a honda or ariens pro? That is pushing it, IMO. Power boost is just a CVT that automatically lowers the gear ration to the impeller / auger when the RPMs drop on the motor. Its the reverse of a snowmobile transmission. Being acquired by Briggs didn't do them any favors. In fact that is what made airens move away from the intek snow motors and look for a new provider ( LCT ) Oddly, i believe the first LCT powered aries was the snowtek, and that was while the ariens machines had intek snows.
