keep in mind what the rear skid is doing.
mono skids to a point do not change ski pressure by changing strap.
this is the issue. the skid uses two arms, balanced against one shock so front and rear arm pressures are a fixed proportion of the shared tension of the single spring. It was designed to go in a sled with a very heavy front end that was higher so the predetermined downward force is not really changeable without effecting the rear downward force. when you pull the limiter on these skids enough to take weight off the front end, your limiting your travel(way less drop out) and your increasing the rear arm pressure. neither is desireable.
one of many flaws of the mono is the transfer rod. It is enclosed, so it is hard to see where things are when your on the sled compared to most other coupling systems.
what you might be finding is that you have too much spring pressure, causing the sled to sit too high witch on this skid, also increases front arm pressure, lifting the front end. The other is the transfer rod may need to have a different spacer on the inside as with the lower front end and higher back, you might be reaching the end of travel before it couples when your on the sled. this is hard to tell as you can not see inside the rod.
the other question that comes to mind in regard to this front end, did you realign the front end after the flip? sorry if this sounds like a dumb question but sometime people forget that the front end of these sleds are crapy and the toe changes alot with any height change. if you did the flip and never changed anything else, your sled would now have more toe in than it did.
also, where is your ski carbide bias. these skis like to be neutral for best handling and ease of steering, a little rear biased will make them turn harder but still go straight. bias on the front will make them turn super easy and to much will make them try to continue turning when you have stopped input.
the only way I have found to check the rod settings inside the transfer rod on a mono is to unbolt one end, set on sled, then measure the travel it has from when the bolt is in to where it bottoms out.
