Thanks. The defy series between a M and M/L is .5 degree difference in seat angles. So I'd imagine that wouldn't make a huge difference on how far back you'd have to set the seat on the rails?
And yes, the body scan thing I got told me "functional height" was 5'10.5" with shoes on, when all other measurements I've taken and at the doctor I'm 5'9.25" without shoes. No way shoes add almost and inch and a half of height!
