The Ergon bar-ends' angle ARE adjustable independently of the grips.

I have the early version with the tiny bar-end; it is indeed close to worthless. Not only is it very short, but it is rather sharp on top so it cuts into the palm a bit. On aa few other bikes I use the BBB brip with normal barends, I find the BBB ones superior, they are softer so conform better, plus are cheaper. The ergo-stiks weren't cheap.
