In flats I don't mind 11 s at all, but in the hills I liked the ability to move more quickly down the cluster when transitioning from sitting to standing.
That's what I mean by the wrong cassette. An 11-speed 11-28 has all the same cogs as the 12-28 10-speed plus an 11t so it will shift exactly the same as the 10 speed cassette in the 12-28 range plus it has and extra gear
