Stratehm proxy is fantastic, my S9 (B3 w/ updated firmware) is more reliable than my S7's on zpool, have only had to reset it once. (This was most likely due to messing around and testing stratehm proxy to a tethered cell-phone and not due to zpool, but there it is.)

Is there some advantage to ckproxy that stratehm does not implement? I don't think I could ask for much more functionality.
