I also use Ergons, although not the ones with bar-ends. My Cube actually came with their own version and, although I liked the concept, they weren't actually all that comfortable. Buying the Ergons was a bit of a gamble given the price. But I love them. Instantly more comfortable than the Cube equivalent as well as being very nicely put together.
By the way, the only reason for my not buying the GP2's or larger is their unique ability to snag on people. I couldn't use my bike here simply because of that problem. Too many tourists just walking all over the shop.
