Never heard of the smart cinch, just looked it up and..... wow, looks great and I like the price too! My friend's saddle is a pain to cinch up (no rollers at all). I think I will definitely go for the smart cinch! Thanks for the tip.
Although I am more of a traditionalist and prefer a leather latigo, a well made (not a cheap) nylon one is easier to cinch up since it doesn't bind due to friction and will last a life time without stretching the way a leather one will. My riding partner has been using his for years without fraying - and even if it did, a cigarette lighter to it will seal the fray.
