I like my horses to have their own rope halter and flat halter. I keep a spare rope halter and lead in my trailer, but Speedy's regular rope halter has special rings to attach reins for riding which I keep with my trail bridle. It doesn't have its own lead rope. Since Sydney's rope halter fit both him and Speedy, I kept that halter and lead hanging for quick use, but it was too small for Izzy. Soooooo, that halter and lead are now Speedy's alone, but that left me one lead rope short.
I am extremely picky about lead ropes which means I only use clinician style yacht rope leads. They're definitely pricier than a standard 10 foot poly lead (almost $30), but they are oh so worth it.
