You've read the treatise, had the fitting, written in the forum.........
now go ride your bike.....as long a ride as you'd normally enjoy without excessive fatigue or pain....and report back!
Proper fit is an investment. Part of the investment is riding, fine tuning, comparing notes.....
Don't rush to judgement- but get some miles in! (I bet your weather is 30 degrees better than mine today;-))
