@AngeNZ, I've found the X to be reasonably forgiving with wicking.
With Rayon, I've found out that you don't need to thin the wick tails at all with a 2.5mm ID coil. Just fluff and comb, cut to length using the edge of the deck and gently tuck into the wells and try to keep it nice and fluffy.
Running a simple 27AWG (0.34mm) 2.5mm ID 8 wrap SS316L RWC (Round Wire Coil) at 0.73 ohms.
