HI Unter, how can one tell which has greater strength just by a few photos? I'd planned on doing the same thing with the ends on the sample pannier rack in the pictures; weld them into the ends of some tube stock which will be the loadbearing end of a DIY pannier rack. I can't tell how deeply inserted they are into the tubing yet I assume they'd be deeper than the shallow tangs on the rack tabs. I also assume the example ends are round like the tubes themselves.
