1/2 cordless impact opinions

I recently bought a Kobalt 1/2" drive impact for my shop. I just have the little battery but plan on buying the bigger one before racing season.

Seems to have plenty of balls... I like the lightweight of the small battery. When I pit for my buddies dirt late model team on Saturday nights I can barely lift his DeWalt HD impact with the 14" torque stick attached...God I'm getting old and feeble.
