Please don’t take this the wrong way as I am sure you understand your saddle. However that sounds like an adjustment issue. Did you try bringing the prusiks on the actual bridge loops up a little? This changes the angle of the holding pressure. When mine is up on the high side of my loops it literally takes enough pressure off of my thighs that I can fit my fingers under my legs and the webbing. I am assuming based on the bridge, that the H2 saddles would be the same. Although there is a lot of cupping shape in the H2 so I am unsure. That problem is not a “single panel” problem for all single panel saddles as long as they are adjustable on the bridge loops. Just like it takes adjusting in a two panel to find the sweet spot, single panels need fine tuning as well at least in my experience.
