I'm interesting in the TT answer as I'm ordering the same gap and lob wedges, and getting the 56/14 because my clubmaker told me it bends to 55/12.5.

Depends on you and where you play.  Diggers vs. sweepers need more bounce.  Dry, fine sand bunkers need more bounce.  Wet, course sand bunkers need less bounce (almost hard pan conditions). 

Since the two new wedges you like have either mid-bounce or low-bounce (of the available options), it would seem to me you would probably be better off with the 56.11 bent to 55.10. It's hard to say without doing a proper fitting to see how your divots look and how your marks are on the sole with a lie board, but that represents a reasonable guess.

I would go for more bounce.  You have a low bounce lob wedge and gap wedge.  I personally believe that you would benefit to have a high bounce option for bunkers, heavy rough, soft consitions, etc.
