Sail Track Replacement

[JChorlton]

So ...I've pulled the mast and most bits look good (aside from the crusty mast step). I'm thinking that I'll have to drill the rivets on the sail track, have it stripped separately and re-use it. To reduce the friction I might have to install either the Battcar system or the Strong Track system.

My sail-maker likes the Strong Track system https://www.tidesmarine.com/?page_id=61 and seems to think it would work best (no joints, less of an offset from the mast and reduced stack height of the slides). Does anyone here have any experience with the working life of the Strong Track UHMW-PE track? Would these have a lifespan similar to my black Delrin sheaves?
