I am guessing you are cutting too low for where the stripe kit is set at...hence the dragging and that could also be affecting how the deck cuts.
I would check that out first. If you are dragging it around, raise it up and see if the cut improves.
I was thinking that. I cut between 2.25-3.5. I noticed the x cuts higher than my old rh. Meaning I cut on 2.75 with the rh and to get the same height on the x I have to go to 2.25. So I'm cutting low often with it. Also the blades have a drop on both sides compared to a standard high lift blade. I switched them for the standard blade which made it worse because the blade is more up in the deck.
