That is a very good point regarding the running of the cables. It took a couple mistakes to get mine right but it has been very reliable since then. The adjustment is really not that difficult (unless I've just gotten used to it).
FYI, in addition to the cable, OX does offer air and electronic actuation although they are a little new to the market for any realistic reviews.
Definitely not difficult to adjust, just a slightly more involved install then the Arb.
One tip to anyone w/ an Ox...check the bolts holding the end cap on the carrier! Then check them again. And then when you're done that take them out and use red (that's R-E-D...you know, the extra-strong-needs-heat-to-get-back-off kind) loctite to install them. I had issues w/ mine engaging on two occasions and both times it was those loosening and a couple dropping out.
