Which is more important, strikerate or ROI?

I was looking through selections calculated by my bayesian system and came up with two approaches to a set of selections. Other is high strikerate low ROI and other is other way around. Naturally in perfect world one would take both, but what would you choose if you had to choose either or from below?

System A

  • 867 selections
  • 246 winners
  • Profit of 53.25 points
  • Strikerate of 28.37%
  • ROI of 6.14%

System B

  • 289 selections
  • 8 winners
  • Profit of 225.83 points
  • Strikerate of 2.77%
  • ROI of 78.14%

What would you choose?
