The pressure plate on a two screw lig is something I've never seen anywhere else except in photos of your ligature. And yet it seems like a good design unlikely to have serious faults.
I will call everyone's attention to the fact that on Pete's ligature (as on all well designed metal ligs of this type) the two screws are about as close as they can be to being tangent to the OD of the mouthpiece AND they run through long bosses, so the tendency of the ligature to bend at the screw location is minimized, unlike the Hype-hype-hype-irion, where they've got the screw up on a couple tall plates that will clearly bend preferentially to putting tension in the band.
This is the way hose clamps, V-band clamps, zip ties, the string ligature, all work, because of those laws of physics things we techies learn early on in those classes the artists don't have to bother with.
