I'm just getting into this sport myself and recently bought a
halter/bridle combo made of biothane with matching reins that have
rubber gripping which is great for the rain. Sportack has a great
selection of those kind of accessories and they are great on their
service. SPORTACK has a catalog on the endurance web site. I'm really
pleased with the whole setup. (Make sure when you use biothane products
you use quick-release snaps on tie-offs. Biothane WILL NOT break, so in
emergency there must be a way of escape.)
Sounds like you got a great new horse...ENJOY!
