I borrowed a friend's Herm Sprenger D ring snaffle with a smooth roller in the center, and my horse who has never produced foam that I have seen, was dripping a little foam as we worked today. I will say his mouth was a little too busy with the roller (I assume) but FOAM??? This but cost my friend about $150 US dollars.
So now, naturally, I am questioning whether or not I will invest in a more expensive bit! Quite a big expense when I have something that works okay.
SO, what are everyone else's thoughts on purchasing the more expensive bits? Do they have the technology that the cheaper bits don't have? What about metal quality? I do know about "renting" bits but would like to hear other thoughts before I commit on a rental...cause quite frankly, I will probably be renting to own regardless!
