?15 Rik, I didn't really think the extra features were worth the extra money.
such as the waterproof cover on the Fox. The drennan is waterproof anyway, The loop for keeping your flask upright, nice touch but I can live without it. The rig wallet, I don't think I'd have used it. The dedicated compartment(I think it is,it fits) for large fox system box, ever tried to fill one of them with tackle? the medium holds everything I need, and fits the drennan front pocket spot on (wonder if drennan knew this).
As you said, I'm not taking anything away from it, excellent bit of kit! I had every intention of getting one til I saw the drennan.
