I prefer 23/22 with the one. This gives us 14 numbers to hit White off the edge of our prime next turn (rather than 12) and removes a target for White's builders on the other side. The extra flexibility of staying on the 22pt on that side is largely illusory, as we won't want to leave the 21pt and leave two blots inboard anyway, except to hit an indirect shot in the outfield.
