Full Belts discussion

Quick question for those of you who experiment:

I own a CS-500, which locks in quite well as long as the hip band is pulled tight—sometimes uncomfortably so. I suspect part of the issue is that the band itself is thin (around 1mm), making it easy to flex. This flexibility allows space to open up at the front when I lie down and pull upward. When my measurements are on the smaller side, I can actually slip out, though it takes some effort.

I don’t currently own one but am considering purchasing a Neosteel Arch. From what I gather, its hip band is 3mm thick and significantly less flexible than mine. However, having used a Chinese-made copy of the Arch from DHGate, I’ve started reconsidering whether a full belt with a crotch cable might be worth it.

While that cheaper version isn’t quite on par with the original Arch (which likely offers better comfort), placing my CS-500 cage onto a thicker, stiffer hip band feels like it could be the ideal setup. It would eliminate the hassle of a crotch cable while providing more security through increased rigidity.

Has anyone tried something similar? Any thoughts on this approach?
