Martin (and getting back to original post) I agree, solids are a worthy addition to a track car just becuase of the increased control they offer and nothing at all to do with the extra RPM.

When you hear cars come in at the end of a track session and they are down on power and clattering away cause of the hot oil not working the hydraulics as well, its easy to see why people want shot of them, its that reason that I converted my car to solids more than anything else.
