I'm not much of a gear-spacing weenie, but if you don't need the ~1.5" lower gear that a 28/34 provides over a 28/32, the 11-32 would give a little nicer spacing between ratios.

Since now is the time for "winter thought experiments", you might consider going even smaller on all the chainrings, since 50/11 is a pretty high gear in my estimation. A 48/38/28 can be built on a 130/74 triple for starters, and a 38T middle ring should shift to a smaller granny ring (like 24 or 26T) much nicer than your current 46T.
