You should also consider the Schafer system, doesn't go through the mast, comes with it's own rigid vang, articulated track allows for more forgiving furling when dropping in wind.

'have to agree with Jim, since the Schafer (don't know which one he likes) has it's own track with a feathered feed, once you get the leading bracket in place (along with the halyard) it's a done deal, never a kink or hassle..... it's a one person job. I leave my main furled completely when not in use, so only have to feed it when I raise it for the day.
