Some "Traditionalists" may complain these are too supple, but I find horsehair to be brutal on my hands. If you are colt starting, these are probably not what you want for starting, but they should be what you are able to use before going to the double rig with the bridle and bit setup.
My only complaint is that they are stored not in round rings, but rather folded together which leaves a LOT of kinks, and kinks in reins lead to miscommunications with the horse. I washed mine in warm water and a good amount of fabric softener, then stretched them out full length with a little bit of tension. There are still some kinks, so I'm going to rewash in some warmer water and try drying in a circle around a barrel. I am sure the kinks will eventually fall out, but don't plan on using them out of the box. Still a great price on a quality product.
