I will go with 24/18 21/18 to make the opponents bar. I will leave my 5 point for now, since only 55 and 53 will get white's back checker out safely. I should have lots of opportunity to hit/make points with all my builders.
My first inclination was to play 11/5 8/5. Xtreme Gammon prefers 21/15 13/10*. I'll admit that I never even seriously considered that. I hope some experts chime in on what they think.
