re: OB Recommendations....on cordless tool sets

1/2" impact is the cats arse for sure... i have the 24 volt brushless kobalt which is a torque monster, and now the 3 speed ryobi. we use both for racing mostly, and will change several tires on a saturday night if need be and have had zero trouble. the 3 speed ryobi honestly has been the one traveling with us as of late just because of how light small and fast it is
