Well, as long as the power steering pump behaves at least...the hydro's stall out too (Milemarkers are great, but you still have the power steering pump flow as a limiting factor for how long you can pull for.)

Yeah - Power out (Letting the load down easy..) is pretty much the only way to heat the drum enough to worry about...and I'm typically in need of power in...if I'm doing power out, I'd take it easy and let it catch up on cooling/splash it, etc.
