Question about Racer Tech Medium rate Springs……..

For those of you with these medium rate springs, I have questions: (my ride is a stock 2015 900 XC):

Is the ride noticeably smoother?
Is there more ground clearance over stock springs?
Is there less spring sag?
What is the difference in spring rate in OEM vs. Racer Tech?
Will I be happier with these new shock springs?

My riding is general riding up the woods, not fast, with some rocky trails, but not a real lot. Not interested in going too fast, but a nice general ride with some rips where warranted. Usually just me (180 lbs.) with about 30 lbs. of gear. Racer Tech site formula says to go with medium rate when weight figures punched in.

I don’t want to waste my time if I won’t be happy. Just looking for a smoother ride with enough ground clearance without a lot of preload. Currently have ground clearance of 11.50" on front and 10" rear without me in it. Thanks.
