I think all the responses have been correct. For my input, I'll say that where the stirrup leathers hang is a function of the stirrup slot placement in the bars, primarily. 2 1/2" leathers will allow for a little more flexibility, and I use them in all saddles that I build, unless the customer requests otherwise. 1/2 leather, ranch cutter style fenders / leathers allow for maximum flexibility, and do allow you to put the point of the stirrup position slightly ahead of the true stirrup leather line. I use that style of set up on many saddles as well. JW
