If you are needing a winch it's likely you are trying the roll up the sail while it is filled. The sheet should be mostly free, just enough tension to be sure the sail rolls up clean, but not too tight. Often works best to furl sailing a deep reach, with the genny blanketed by the main. Alternately in lighter breezes do it head-to-wind with the luffing sail putting the right amount of tension on.Also remember to keep a light tension on the furling line while unfurling the sail to avoid overrides on the drum
As far as line size goes, for handling larger is better (easier on the hands), but don't put so heavy a line that it overfills the furling drum. A good non-stretch line helps. On our 24' race boat we had a small (4mm - 1/8") kevlar furling line with a larger (10mm - 5/16") cover slipped over and stitched to the portion that did not enter the drum. This kept the line in the drum small, but left you something to grab at the cockpit. This combo would be too small for your boat but you could do the same with larger sizes.
