I would recommend bullseyes where you are only trying to contain the line and lead blocks where the line is deflected or turned. Using a ratchet block as the aft articulating block is a good idea.
Be certain that the first articulating block behind the furler is positioned as close to perpendicular to the drum as you can get it. Then by imparting a little drag on the line as the sail unfurls you will get a nice wind.
