XT cranks
Best value in cranks as far as I’m concerned. Great rigidity and quality.

Going Short
I've read about using shorter crank arms and decided I'd try it. These are the same Shimano crank arms that were on my bike, so I already knew their quality. I went from 170mm to 165mm on a steel suspensionless mountain bike. Like the greater clearance and so far the pedal motion feels great. Very easy transition to make.
