I have finally earned enough SP to max out another SR card, but what do I pick? Wish I hit MLB King or Taishin so I could use it as my 4th speed card over welfare Spe SSR, or Mayano so I can run 3 stam since I apparently suck at training for med/long. Thinking Biwa? But people seem to be able to max both speed and power without a power card, so I apparently just suck at training all lengths general.
