You haven't stated what your issues are, I'm assuming dry hits? In that case it might be
1. Hot spots on your mesh strips,
2. The ultem insert can compress the top of the cotton, hence some initial minor raking could be required, I rake mostly from underneath.
3. a n other..
this cut looks about right

Fluff out (not done below), maybe a bit of raking from below, then cut a slight angle (black lines), fluff again

You want the cotton to sit nicely to the bottom of the deck but not too much, after soaking the cotton let it expand and see if it needs a trim horizontally at the base, making sure the cotton sits nicely with no gaps, to help prevent leaking.
