Glad my thread was useful to others!
What exactly about the RB021 isn't working for you? Not finding a good position with it? Is it the deep drop?
Cause I will admit, it did feel kind of awkward at first. But I was used to wide risers, so I'm thinking it probably wasn't so much the RB021 itself, as it was just getting used to bullhorns in general. After a few rides I have to say it's feeling pretty damn good. I'm mostly riding in the flat section of the horns. Barely ever get on the tops, except to grab the brake. To me, control feels a lot more solid on the horns, especially for sprints and climbs (already finally did a lot of that during my ride yesterday). It's certainly grown on me, and once the longer stem arrives and my position improves, the RB021 can only feel better.
