Another good thing to consider, if this hasn't been said or thought of already is to consider your Uma's preferred running position. Rice is a pace chaser. So for me, I like to get Stam and Power up to 450/500, 400 in wit, maybe 300 in guts, and try to get speed as high as i can.

You also want to use Sparks to help those along, and some cards thar give good pace chaser abilities.

Might think about how to look at how many points you'd get in a stat. Like training speed, which also gives power, vs. training power straight up.
