what's the problem, can't you put up the sail you want and then put it away after use? Sounds like the boat has new roller furling gear...but no sails sized for it??
I've never heard of any issues related to furling a particular sail or material - the sailmaker who will fix the sail can confirm that for you. There are a number of common issues when coverting a sail to roller furling:
1. is the sail luff taped and the tape the correct size for the furler extrusion
2. The furler units takes some space out of the hoist, if the sail is a full hoist, the foot may need to be cut to reduce the luff to fit. If the sail is NOT full hoist, then a leader may need to be added to head, so the furler swivel raises to the top of the forestay.
3. you need to add a UV cover
Coverting a sail to roller furling can be expensive, if the sail needs cutting down and is old, it can make sense to just buy a new sail, sized for general purpose use in typical winds, for example here in Boston I want to get a 130%. Otherwise just do the sail you expect to use most often.
