You do want to check the tape size on the jib to make sure it is the correct size for the foil. Figuring out what size tape is on the jib and the groove size of the foil may may take some research.
On my CS36T I easily see the effects of friction on raising the jib. I apply McLube to the foil groves, mainsail track, and the luff tapes at the beginning of the season. I can then raise both the jib and main to full hoist by hand. By the middle of the season, raising either sail requires the use of a winch for the last third or so of hoist, although re-lubing the tape and slides helps some. So friction can have a big effect.
