Who knows about bits please?

[INTHEGROOVE]

Can anyone help or offer suggestions to try please?
Big strong horse,
ridden and going nicely in a loose ring french link in the school, no problems there.
Hacking he is waaay too strong!
Have tried the following:
3 ring gag - he tucks right behind it and REALLY doesnt like it.
rubber pelham with elasticated curb - doesnt pull too much, but he still ducks behind it a bit.
hanging cheek snaffle - seems ok in this but is still much to strong and pulls like a train.
any ideas please?
I think i need something in between the hanging cheek snaffle and the pelham, although i am fully aware that they are both from different 'families' of bits......

I don't like them, but what about a kimblewick? I would say that they are between a hanging cheek and a pelham as they have some poll pressure/curb pressure but not as much as with a pelham.

You can get slotted kimblewicks so that the reins are in a fixed position on the ring (so some/lots of poll pressure) or plain rings so the reins can slide.

You can obviously also change how much poll pressure is applied by adjusting the curb chain - the looser it is the more poll pressure that can be applied (as the bit is free to move around more by the time the curb chain acts).
