Motor recommendation for A4982 + line drive setup?

Having a hard time deciding on stepper motors for a 65# spectra line setup for the my Rostock build with magnetic joints. The whole talk of low amps and 0.9 vs 1.8 degrees threw me off.

The driver is a A4982 1/16th microstep, RAMBo motherboard.

Or is there another motor out there that will be more appropriate?
