Good snaffles so long as you get one that won't pinch. I prefer the ones with lozenges or oval mouths to prevent nutcracker effect from happening.

Pros: Nice gentle snaffle, especially the ones with lozenges

Cons: Nutcracker effect with plain snaffle mouths

Most horses work well with a snaffle. I myself use a racing D, but in general snaffles work the best!

Pros: great for almost any horse

Cons: inexpensive

All my horses ride in a french link, either loose ring, or d ring. The best bit I have ever used.

We use D rings at our ranch. It allows more head movement.
