In my limited experience with jacklines, I've always used a double tether system like Kevin described where you clip to the jackline to move around but clip the other tether to a fixed point when possible. Having two tethers on your harness at all times seems preferable to having tethers stashed around the deck.
I've always used flat rather than twisted jacklines. Agree with others that twisted seems like it would increase the risk of tripping. I've never had a problem grabbing a flat jackline off the deck, and even if it took a couple seconds more, that seems like a worthwhile trade off as long as you're always clipped to something (which relates back to the double tether system).
