Have you even tried a HOG harness? Do you use a crotch strap?
The chest strap may clear your drysuit inflator, but I have read of a few people that it has gotten in the way.
I dove the Dive Rite deluxe harness for a few years, and toward the end of last summer i picked up the transplate. With both systems i used a crotch strap, and chest strap. I can see how it would interfere with the dry suit hose, but for me its never been a problem.
But like I said, thats what works for me
