choosing the right harness

i currently fly a woody valley xpression m and find its alright for most of my flying but its too lively for learning acro.
so i picked up a second hand acro 3 L the older version but found it was to large.
i have test fly the acro 3 M latest model and found it was to small and are there any difference with the newer and older models in size.
i'm 186cm and 87kg
has anyone had much time with the new sol wasabi 2 ?
