My experience with roller furling on other boats, it is likely to be as difficult to even more difficult to roll up. Either way for the 1 up guy 2 hands are needed to do it fast.
Add a spring between spi pole attachment and furler so that the furler drum stands upright. It is much easier to furl than to drop a spi. I gave the furling line some extra length and knot it to the rear beam. So I can furl the sail from the rear end of the boat. Gives you an extra good feeling in strong wind/wave situation, where on usual spi boats you have to go close to the mast. Two or three velcro strips are stiched on the sail where the sheet is attached. If fully furled, the velcro stripes keep the sail furled and you don't need a cleat. It is a very simple system, which can be rigged in one or two minutes.
Cheers,
