I'm just wanting the larger bass drivers is why I'm more interested in the 64s over the 50s. I've read just about everything you've wrote about the sh50/sm60 and would most likely be perfectly happy with the 50s but I'm taking all my subs off the front baffle wall so running stereo will be effortless without running the attic IB with the 64s is what I'm thinking. But we all know I'll add the IB at times as well so might as well call it overkill.
I've seen some SH50s listed by the pair for sale for quite a while and the system you mentioned but if can find 64s used they would be worth the extra money to me.
