I use a 3-Point with wither bridge, made out of biothane with waffle neoprene. I chose the one I did because of the amout of adjustability it has for my growing horse. The neoprene prevents any chafing. My breastplate also attaches by clips. I find them to be much easier seeing as I switch it between multiple saddles. I use a breastplate to keep the saddle from slipping back on trail rides. There are a couple fairly steep hills where I ride.
The love for a horse is just as complicated as the love for another human being...If you never love a horse, you will never understand.
