i need recommendations for a new bit...I feel like my horse needs someone different. I currently ride in a half wonder twisted wire/lifesaver mouthpiece and a jr cow horse twisted wire. I’m thinking I want something with the equivalent severity but maybe get more bend? Something chain mouth maybe? I have no idea. Help!

Maybe a twisted wire loomis?

ive seen a video or two about how to ride in a loomis - maybe try to find one (Facebook or YouTube) and see if that’s what you’re trying to achieve. 

Is your jr cowhorse a 3 piece mouthpiece?  

A chain mouth helps with getting more bend, I like the chain, and dog bone mouth.. All my bit's mouth pieces are either a chain are dog bone I like my bit mouth to be a 3 piece I really dont care for a twisted wire thats broken in the middle. 

You really need to find the mouth pc your horse prefers (yes there are times you need a little more than the horse prefers but you have to start with a base point). Why fight mother nature? Then decide if he needs a shank or even if he needs a curb, then what material curb. It all goes together along with YOUR hands to get success.

Im helping someone now with this issue. Was using a twisted wire dog bone jr cow (which is my least favorite bit of all time) with a chain curb. Her horse was front endy, fighting his face, wouldn't let you handle him, didnt want to collect, super sensitive... and this person has good light hands.

I had her try a chain oring. He still mouthed this bit a lot but was much more comfortable. She could touch him thru the turn, he would collect up thru his body, no more front dump. I personally dislike orings for normal use... I find a lot of people tug and pull and stay in contact with their mouth causing the horse to tug back. Then they wonder why the horse isn't light and add a GM to fix that and the horse dumps even more on the front end.

Both mouths lay on the tongue but the dog bone doesn't conform as well thru the bars like a chain... just a small detail can irritate a light mouth, then add a curb and it worsens.

So I guess if you can find someone  who has them and try a number of different bits you may be better off than guessing.

This is some of the best advice EVVA!

Although, my favorite bit is my jr cowhorse with a dog bone but... I have found my hands get along best with the 3 piece, with a dog bone or a roller, and with the sweet iron, I tend to fight a stainless and a copper... but this right here... is greatness....  We all have a different set of hands.. and with in those... lays the answers

No it is a 2 piece
