Thanks for that link to the wiki link to the horse info. That clears some things up. Sorta. I'm still confused.
Right now, maybe 8 hours in, my horse seems pretty slow. This is only noticeable on a bounty mission when I'm trying to get the perp back to town. The bad guys spawn behind me, and then pass me like was was standing still. I'm pretty much forced to repeatedly kill them. With a fast horse, would I be able to stay in front of them, or does the game alway rubber-band them past you?
The wiki says that that stallion that you tame in one of the early Bonnie missions is a Kentucky Saddler. Very fast. I rode that horse for a while. Hitched it, etc. But, it died eventually, and I guess I'm now just getting random horses now when I whistle? They don't look like the Saddler anymore, and like I said, don't seem very fast.
I don't have the option to buy any "fast" horse deeds in the store. Just slow ones and normal ones. Because I tamed the Saddler, shouldn't it be in the stores now? Do I have to go find one in the wild? Did Bonnie's stallion not count?
