Any thoughts on this bit?

I know it is expensive, I am not paying for it, but just trying it for nothing.

It seems complicated to me, but my horse needs to 'start over'.

If you have used this bit, please let me know.
Thanks!

I haven't used it personally, but really it's not that exotic of a bit. Just a simple ported curb with roller, only with a Pelham option. I wouldn't use it on a green horse, but one who's ridden in a curb before and neck reins well.

Good entry level curb, I think. It's not freaky huge and the roller would definitely help the horse relax some. The port is a gently curving, not harsh square. The shanks have a good bend so the horse is 'alerted' of what your doing quicker then a straight-shanked mouth would be doing (much harsher). It's similar to the one I ride Red in, except his doesn't have a roller :)

Good bit if your horse neck reins and responds to legs. If you need something for direct contact, a three piece snaffle is the way to go, then graduate into something like this. Red, for example, moves off of leg and neck. Rarely do I have to ask more with the inside rein. If he needed a lot of direct reining, then he would be in a snaffle yet.

I would rather go with a sweet iron or copper mouthpiece (tasty), versus a stainless steel one (bland).

Thanks!
The instructions are to use it as such:
The use of two reins allows you to balance the horse with the top rein and tip the nose with the bottom rein, if necessary. The port is angled back slightly to allow room for the tongue and palate. The copper roller is slightly raised above the tongue and requires the horse to lift its tongue to roll the roller, which has the effect of softening the jaw. The loose, curved-back shank helps to soften the poll, which in turn activates the pelvis and frees the back. In contrast, a straight-shanked bit has the tendency to flex a horse at the poll more stiffly.
