I ride exclusively on my big ring (42) and rarely use the two lowest gears on the 11-32 8 spd cassette. And I do like to coast downhill.

I've inquired about converting to a 1x setup at the LBS. Though doable, it would mean swapping out the cranks and bottom bracket as well. (Note to self: next bike, ensure the chain ring(s) are bolted- not riveted!)
