Nutcracker causes a "v" shape in the mouth, which squeezes the bars and protrudes into the roof of the mouth. A dogbose has a "u" shape and is nearly impossible to hit the roof of the mouth.swept shanks give a "warning" to the mouth and straight shanks cause an automatic action. Combos tend to give mixed signals, pulling up on the lips (from the gag) down on the nose via the noseband, up from the curbstrap and down again from poll preasure
tinyliny, for some time now, if I click on a direct link in HF, the redirector doesn't work (in firefox). I have to copy the link location and paste it into a new window to get the link to work. That has been true on all links in HF for the last couple of months.
As for western bits, there are a number of other options. I don't barrel race, but I like this bit:
It has short shanks that swivel, a 1.25:1 pressure ratio, a copper roller and sweet iron links that won't give the nutcracker effect and that curve to give the tongue some relief. I can't speak to how well it does for barrel racing, but my only objection is it is a bit floppy trying to get it into my horse's mouth.
Like that one, skip, but with a dogbone or lifesaver in the middle.
I do like that Argentine bit you posted as well, I'm going to be buying one to see how I like it in my horse's mouth.
I personally like combos as well though. BUT, not for a beginner barrel horse. I use combos when I give a tune up on a horse once in a blue moon because they've gotten lazy (seasoned barrel horse who just decided she didn't feel like listening one day). One ride in a combo with light hands (didn't have to pull like I did in the almost snaffle low port bit she was ridden in usually) and she went right back to being light in the low port. It's just easier on me to use something that has the potential to be very harsh with light hands than to haul on something with less power. Doesn't mean everyone can do it though. Only time I'll ride in a combo for a quick "get it together" ride is when I'm in a great and patient mood, no way am I going to risk getting annoyed and bopping them in the mouth with that kind of leverage. They aren't to fix problems or ti routinely ride in (IMPO), they're for BTDT horses that get lazy every once in awhile.
No single jointed mouthpiece has any right to be on a shanked bit, IMO. That's poor design with cruel intent (atleast in my mind). Posted via Mobile Device
^ combos aren't horrible, I just couldn't see a beginner barrel horse taking kindly to it lol. I have seen some horses use them successfully, I just wanted to make it clear to op that they probably are not the best choice for their horse:) Posted via Mobile Device
