Thanks for your input Neil. I guess the solid 4-prime of White is strong enough to force us to play as pure positionally as possible.

In the variant below (White's 7pt. moved to the 8pt., roll modified from 4-2 to 5-2 to produce a similar decision) the gapped prime is so much weaker of a blockade, that we should just go ahead with the hit&cover.
