I'm not sure how many other TI/AI owners have experienced their sail furling line getting caught under the mast bearing support, but I have on too many occasions & always at the worst times. I have tried various 'simple' methods to stop the line getting caught, but the photos below show my latest version & so far the most effective solution. I initially tried gluing (silicon) the shroud the the mast support, but I found that it didn't last (due to sideways aka movement) so I have added a couple of small screws to hold it to the bearing support. So far, this has work very well.
