I like the idea of spares on the 4 and 5 rather than on the 6 and 3. Granted, my choice risks leaving a shot with a roll of 6-4, but spares on the 4 and 5 look more like the "wave" described by Trice as the ideal way to bear in against an ace point anchor. Take a small risk now to avoid awkward rolls later. That said, the moves are probably pretty close.
