Smrobs - I am not lunging him with the lunge attached to the bit, I usually lunge him first to get some of his spunk out then ground drive then ride. I have the riens attached to the saddle and I had his rope halter under the bridle, which is a one ear sliding headstall. No I would never lunge off the bit.
I thought my bit wasn't a curb, but a snaffle, single jointed? I must be really wrong then! Haha but it is the one in the picture on my beginning post... I thought it was a tom thumb snaffle?
Also I don't have the luxury of 'testing' these bits, I have to purchase them, can you return a bit? I don't live in an area where people keep horses for pets like I do, I live with the only other horses around are amish. We have one neighbor 6 miles away who has 3 horses but hasn't ridden in over a year but I do go to her periodically for advice, but I have turned here more because I get more opinions which is GREAT
