I'm looking to put hard bags on and I noticed threads from awhile back that said the JC Whitney large cases are Givi E360 clones and will fit monokey racks. Has anyone tried this recently? Does it still work with the current cases JC Whitney sells? Is it really worth it to pay and minimum of $310 more for the Kappa cases? I have cheap knock off as a top case and it's performed fine, so even though I could swing the more expensive options it seems crazy to me.
