I agree with JimP, a gap wedge would be useful. I recently bought a Mizuno MX gap wedge at 51/06. This fits well in my MX15's the sand wedge is 55 deg. I notice Mizuno recommend if using the 51, add a 56/11 MX wedge to keep the gap constant, don't think 1 degree is that noticeable to me.
To answer your question regarding bounce for a SW, it would depend on the type of sand where you normally play, lower bounce for hard, grittty sand, higher bounce for fluffy sand. MX wedges don't give you a choice, but lots of others do.
