Here’s my experience:
Pulex is a good bucket, but their rivets suck. Keep a zip tie handy for when the rivets rust out and break and the boab falls to the ground with water everywhere - then zip tie your attachment belt to the boab.
The ninja boab rivet, regardless of how much it could flop around, just does not seem to rust. I’ve been using the same one for 3 years and no problems. The pulex I’d get maybe a year out of it before the boab just fell off the connector belt.
Ettore, way to narrow - definitely wet leg city.
As you use any boab, keep an eye on how it wears. As it ages, it can and will nick your rubber. Keep a lighter handy and burn down the notches and smooth it on out. I give my ninja a quick flame down every time I change my rubber.
