Sounds like a good idea. I had a couple of extra ones made for my older halter/bridle too and I'm glad I did coz the old guy who made them is no longer around. So what did you do about reins, just use some old ones you had or did you have a new single piece rein made? On the National Bridle Shop halter/bridle, the reins are sold separately so you can order split or non-split reins, depending on which you like. I personally like the extra length of the 7' split reins for convenience at watering holes. I went ahead and punched a hole in the end of each rein and added a conway buckle to keep them together. On my old one, I had the old guy actually sew a regular tongue-type buckle on there to keep them together.
I have a rope/lead like rein and a standard english type braided rein, both have quick releases so I just unsnap one side at rest stops to have enough rein to hang onto while they graze/drink.

lengthened out I don't have to bend over him either when he puts his head down. And I have snaps on both ends. It is heavy enough to double as a lead rope, a requirement for CTR's, you have to have a halter and lead with you during the ride.
