Looks like I should've given the '65 Astros more consideration. I was too scared away by the awful-fielding SS options, but clearly that hasn't been an issue for jmissirlis.
Our offenses have nearly identical production so far:
'65 Astros: .255/.339/.378
'66 Astros: .255/.340/.379
Clearly '65 pitching options are making the difference, though those numbers are relatively close as well.
