I've been using the KUIU for the last couple years, has worked great, nice and compact. This year switching to the ACG CUB for added protection and extra pockets (had some issues with the KUIU letting in too much dirt). So far I like the CUB, little bulkier but don't think it will be an issue and worth it for the extras.
As a side note, I have a badlands bino carrier I'll sell for a good price if your interested. It's a few years old but never used, magnetic closure. PM me if interested.
