Looking for suction suspension opinions

Hello everyone, been an amputee since 2007 and its time for a new leg so looking for opinions.

I am an active BKA. I don't run, but workout for 2+ hours a day. Mainly do bodybuilding and occasionally do HIIT stuff.

I have tried pin lock and hated it. My stump is too short so I piston a lot and its painful later on in the day. Once I start to loose volume, stump turns into a soggy mess. So no PIN.

I tried elevated vacuum by Ohio willow wood (limb logic vs). The system is amazing when it works. unfortunately, it didn't last long. The outer sleeves are way too fragile. I was buying new sleeves every month. Then the pump stopped charging and my insurance refused to help.

I then got a Ottobock harmony HD pump from a fellow amputee. Decent system, but same issue as the limb logic vs system, stupid outer sleeves are too fragile. Its also heavy. It stopped working and I got it rebuilt; $600 for the repair. It just stopped working again last week.

I saw my leg guy this AM and I brought up suction. I talked to rush foot (that's the foot I have) and they recommended suction for my activity level. Just a simple one way valve.

Anyone here have experience with suction?
