If he won't frame try a Sprenger loose ring with aurigan metal, I tried it on my guy but it was too small but even that short 5 min, difference was huge!!! Just need to buy a bigger size.
I have the same problem with my guy. He evades the bit and won't listen when you ask him to frame a bit. He's super smart so sometimes that makes it a bit hard training him... I'm sending him to my coach for some training for a month to help with that and also help teach me how to stop him from evading etc. I've tried flashes and everything but it doesn't work. Still trying out bits to see if that will help!
