As always P8nt,

Has a great answer, It really is the horse. Some just trailer well and some are nervous wrecks and come out all frothed up.

I have used a couple different tie straps, and haven't had any worries. I always wondered if their was trailer accident what would happen? Is it better for the horse to have a little extra lead?

Anyway .. some of the breakaways are good ideas just for the fact, they will do less damage if they feel they accomplished getting away from whatever spooked them.
