Making the bar-point is automatic, 8/7.
It's too dangerous to leave the remaining blot on the 8-point then (could have been handy otherwise to build the prime), because with 2-6 you'll hit that one, and I want to spare an extra shot just in case. So that's 8/7(2).
Now I think it's better to split the anchor on the midpoint for the same 'worst case scenario' 2-6.
Think 13/12 8/6 8/7 will be best.
