Sprenger WH Ultra Bits?

[Doublethyme]

Apologies if this has been covered before, but my search function doesn't appear to be working at present.

I need to replace my existing KK Ultra bit and was looking at the WH Ultra range with the little roller in the middle or the rubber ball.

Anyone had any experiences good or bad with these bits?

Yes I've used one, on my last Horse. He was a nervous lad and used to chomp on the bit. He loved the roller and it really kept him pacified without being over-active. Have a look here, cheapest place, fab service and quick delivery. You get them in a D ring as well.
