As often with 11 there's plenty of legal moves. If you don't see your favourite here, do shout!

Enter and make the five point for sure.  Then for the final ace I think it's best to split the runners.  8/7 is too loose and 6/5 does nothing for us.  Splitting gets the runners moving and puts pressure on the blot on his five point.

XG  likes slotting our bar point more than splitting. Not by a lot, but by enough.
