The best thing is to have a seat that conforms to your side. For me the typical euro seats put pressure in one small spot so, it doesn’t matter what kind of rib belt you use it’s gonna get through. The Ribtect seat/belt system is pretty much it. If there’s anything better it’s not going to be that much better but you’ve got to get the right size.
