I figured you had done it right GB. It was a good question because anytime you use different mounting holes for your skid it will change track tension and should be noted.
My comments on the vibration and noise thing is from my experiences with little wheels when we did a lot more of the drop and roll things in the past as tracks got taller. Now the 3" is starting it again for some.
I will say too, with stock rails I have no increase with that at the same angle.
I know why you ramped up the FTS preload on the stock skid. That spring IMO is the most important to be "personalised" on today's sleds.
It's best for climbing up on the powder to be set with minimum preload FTS. High preload with a soft spring can be tippy on the trail too but if your bottoming what do you do?
I'm about 245lbs dressed so the stock spring was worse for me lol. I used the rear spring preload to help when the snow allowed. So more planted was the result (and why I went TS rear this season) but still darn good for stock IMO.
My "personal" spring is one I've used since I "found" it 10 yrs ago lol. It's an old Holz dual spring set-up that starts a 100 lbs when both springs are free and crosses over at .75" of shock travel (the main "personal" part) to a 250lb main spring (personal TOO but not as much as the cross over point). It has seemed to work well with most standard FTS's valving too because usually that one is heavily dampened on the rebound side and light on the compression side for me. Probably why I don't use the coupling part on my TS skid very much too.
Any how something else you might want to try to make an "all rounder" sled.
It doesn't matter which hole you are mounted in
