I have the Tides Marine Strong track on my 31 mainsail and it is one of the best improvements I've made to the boat. I can get my sail to the mast head by hand and only use the winch for final tensioning.

I use McLube on my track, I have steps so it isn't a big deal to go up the mast, and then can do the same. You have to redo it about every 6 months.
