Trailhorserider and I have clashed on this one before :)
So I am going to explain the best I can about balance of a bit and how the swept back of the shanks contributes to the bit and how it balances on the bars, neutral position and engaged. I don't have a TT bit so I used some bits I own for the pics but hopefully you all will get the idea.
I am guessing if you were to balance a TT bit on your first finger and pinky to simulate the horses bars it would hang exactly straight up and down or pretty close. If a bit is balanced in this manner than the horse has to be very flexed at the poll or collected to keep the bit in the neutral position. If he has his nose out, the weight of the shanks and the reins automatically engage the action of the bit.
The first bit below has the swept back shanks and you can see it balanced on my fingers that a horse doesn't have to collected or flexed at the poll to keep the bit neutral. The short shanks have minimal leverage and the independence of the shanks allows for direct reining.
The second bit is obviously a more advanced bit with more leverage and fixed cheeks but you can see from the balance of bit it still does not require a lot of flex or collection to keep it neutral. The port is still low and it provides tongue relief.
The third is a spade bit which is still balanced in a manner that it doesn't require a ton of collection or flex at the poll. But the angle of spoon comes into play now. But fitting a spade to a horse is a whole other subject..
The fourth bit I imagine would be balanced quite a bit like a TT I imagine. It is straight up and down in the neutral position and therfor the horse would have to have a very flexed poll or ride very up in the bit to pack it. Even though the mouthpeice doesn't look severe I would consider this bit for a very advanced horse with an excellent headset.
It is not just the mouthpeices or the size of the ports and shanks that make a bit severe, you have to take into consideration the balance of the bit.
I DON'T LEAD 'EM AND FEED 'EM, I RIDE 'EM AND SLIDE 'EM.
