Interesting, what you consider "flat lack-luster", I consider "simple and clean-lined".
Just goes to show why there's so many kits out there to choose from since we all have different taste.
You might try the Churchill clip. The tubes are the same as the El grande, not sure if all fittings are, but you could always turn to churchill dimensions to fit your clip. I don't think i've seen anyone do churchill parts on the top of an El Grande twist kit.
