Yay Vidaloco - the RIGHT way to tie! Last time I saw a youtube vid attached in a thread on this question they actually did it the wrong way! You reckon tying any other way makes the knot tight? I've never seen that, but I've seen them fall off plenty of horses when they were done up the wrong way.
I add my count to thinking rope halters are good. Training, riding & otherwise. They are strong and simple, no hardware to break, completely washable, I think they look better than many and they're cheap to boot(I make them for around $7AUD).
I also add my count to those who advised against using them to tie firm - in a trailer or otherwise, and not to leave them on a horse unattended tho. They are strong enough that in case of accident or the horse pulling back, it's likely the horse or other equipment will break before the halter does. I use a 'tie ring' to avoid tying firm. I think these sorts of gadgets are a great safety measure no matter what kind of halter you use.
A couple more tips... avoid halters that have extra 'pressure point' knots over the nose or poll. Fit the halter so that the nosepiece is well up off the delecate area of the horse's nostrils. If you buy a halter who's loose ends aren't sewn together, put a couple of stitches in them - more convenient that way. While you're at it, put a few stitches through the entire fiador knot(under the chin) and stitch the loops you attach the lead to together - the fiador has a tendency to loosen & come undone over time, especially if you're using those lead loops separately & it's a bugger to retie, so eliminate the possibility before you start.
