Got the EOS mounts and they are some what flimsy , but that wasn't the biggest of their problems . The bottom mushroom bolt part hooks up fine with my new KAPPA 21's , the top is where the problem lies . There is at least 1/4 inch slop where the top EOS male slides into the female locking devise on the KAPPA saddle bags . I don't know how the other ones are but these EOS units are defective in that regard . I'll have to figure out a shim of some kind to prevent them from rattling around .
