On another note, in bits I use a 3 piece jointed roller bit with Queso. The mouthpiece looks like this, but the shanks are S shanks. I know who made it but my brain wont work and I can't think of the guys name. Ugh. He was at the NHSFR. He was selling it for like, $70, but its a really nice bit.

Although the reason I need to use such a bit (aside from a snaffle, curb or spade) is because he happens to have the woah problem (the problem where he wouldn't stop if he ran into a wall).
I think those old bits with the big conchos on the sides are so cool. I got the pleasure to take a look at one first hand. A guy was trying to trade it and I was going to get it buy my dad wouldn't let me. it was super cool though, and it really wasn't as heavy as some bits I have.
They look kind of like this, but most of them have 3-4 inch conchos, instead of these small ones:
