Tough call... like you say, the FE has benefited from the years of refinement. It's basically a more modern superlight, except for the SL's Marvic/Akront wheels... which definitely do it for me. So if I had my choice, and was sure of the condition of the SL, I might go for it instead of my FE. But I'm very happy with the FE - I like the understated Silver and minimal graphics.Since it's mostly FE owners in this thread, I was wondering if any of you would rather have a Superlight than your FE? The Superlights are arguably more collectible (at least at this point in time, but I think the difference will tighten up with time) but the FE's benefit from the evolutionary changes that seem to address most of the shortcomings of the earlier bikes and make it a better riding, more reliable machine.
