Luff slides and fittings: how to pick the best - Practical Boat Owner
My main used to be hard to lower and was fitted with a downhaul. When I replaced this my sail maker recommended I had intermediate roller cars as well as roller cars on the battens, it now goes up by hand and comes down so quick I removed the downhaul as no longer necessary.
Probably quite a different beast than the OP has.
