Re-tooling for New Position

I'm moving from skid steers and mini ex's to heavy construction equipment at a new place. My tools are mostly 3/8 and 3/4 drive, seemed like if the 3/8 won't move it the 1/2 doesn't do any better so I go straight to the 3/4. Will this work on heavier equipment or will I be better off starting with 1/2 drive and going to 1 inch when that is lacking?
