I actually tried both, and gave away the pair with the integrated bar ends. They are adjustable for angle, all right, but just aren't comfortable, and that's what it's all about. The small size is for small/medium. The large are really big.

I ended up trimming my Ergons with a hacksaw so I could keep my Cane Creek stabilizers. If I had to choose, I would take the Ergons alone, but since both fit. . . .
