^^ Ooh, I would stay away from that bit, it has so many things that are way too harsh for what you need. Between the twisted wire snaffle, the gag bit, and the rope hackamore all in one, IMHO, that is too much for any horse. Especially a young one. I don't personally care for mechanical hackamores but if that is what you want to use, then just be careful and remember to be gentle. I would suggest that you go ahead and get a loose ring snaffle too (they are pretty cheap) and work with her to get her more responsive to the bit. If for no other reason, then for re-sale value in case you end up having to sell her someday. There are many people who will completely overlook a horse that only rides in one kind of headstall, i.e. "Horse does well in hackamore but pushy in the bit". Too many people will go directly to the next ad. Plus, if she were to be injured someday where you couldn't use the hack, you would still have the option of a bit to ride with.
I don't believe in covering up a training gap with a harsher bit. If she is young and doesn't really neck rein yet, then she needs to still be in some kind of ringed snaffle. For a curb bit, Sunny posted a great one but that should only be used on horses who neck rein well as it doesn't allow for one rein correction.
One thing you can do to get her more responsive to the bit for the stop is take her into a roundpen or some other small-ish area. Urge her into a long walk or a nice slow trot(if she has one). After about 4 or 5 strides, ask for a stop with seat and reins. Keep the pressure until she stops, then release. If she tries to push through the bit, then do a one-rein stop. It will take some work but the results will come and you will have a much more well-rounded horse. Once she starts to stop when you ask for it, just keep up at the jog and ask for the stop every few steps (remember to keep the reins light). She will start to anticipate the stop and that will help her cruise control too. Before you even realize it, she will be parking it at the first pressure on the bit.
