Where could I find a bit like this , low port with swivel shanks? Is there a website or should I hit the tack stores?
I have found a Billy Allen that I may buy ...Just trying to decide which may be the best one to try.
I was thinking of trying this one it is 6" cheeks BitLogic from classic equine and I also looking for curb (low port)
Hmm, I don't really know though...would the Bitlogic bit be the same idea of the tom thumb?
This is the type of bit I use to transition from a snaffle. Remember that they are all "curb" bits because they work off the curb chain under the horses jaw rather they have a high port or low port or snaffle mouth if it has shanks it's a curb bit. After you get him in a curb bit don't be afraid of a higher port as a next step. The higher port helps with vertical flexion and is often more comfortable for the horse.
The ported bit you are looking to get is a really nice bit, IMHO. I ordered it from that site when I needed another bit and it works wonderfully. It is very balanced and mild for an excellent price. Good luck and I hope you are as fortunate with it as I have been.
