I have been riding a compact with 12-25 and feel I spin too much up hills on the 34 but like the 50 upfront to ride on flats (using most gears in back on rolling hllls)

Never get to the 12 unless going downhill where i would want an 11

Don't want to slow down cadence too much either

What are thoughts on going with 11-28 with 11 speed and either mid compact or standard?

Was thinking of mid compact as good compromise but bike shop recommends standard
