Ecogold! I've been using ecogold saddle pads and half pads for 7 years and I'm in love with them. I can instantly see the difference in the horse! Also the half pads are reversable so you can have one side a classic white for shows, and another side a spunky colour for at home!
THINLINE! If your horses saddle fits good thinline is the only one that won't mess up the fit of your saddle but will still offer protection to your horses back! I swear by my thinline! I will never use another half pad!!
