There's nothing wrong with crossties. O_O How else will you train a horse to stand crosstied if he never gets in them? Gracie wasn't too keen on them at first, so I tied her in between two sturdy trees, I held the slack on one end so she did have a release if she needed one, and it took her an hour or so of trying to spin around and getting stuck before she realized just to stand there. Sure, she knocked herself over a few times, but she's much more well-rounded now because of it. Once she quit thrashing, I would stand with her and correct any movement with a tap of a dressage whip. Now, she crossties perfectly, and I can leave her there without the fear of her trying to spin around and trapping herself.
Granted, if your horse doesn't already know how to tie, he needs to learn to tie normally before he can learn to crosstie. But no, they shouldn't be abolished, it's a great set up. O_O
