Having just swapped from a pre-superlight Heckler to an Uzzi SL, my view would be that suspension performance wise the Uzzi beats the SC hands down. It climbs as well, but in a different way, but DH it's amazing, being more supple and without the braking induced stiffening of swing arm bikes.
If SC have managed to build a bike that works as well as the Intense, that doesn't bob, but is only 1/2 lb heavier than a superlight, then they've got a winner.
Maintenance of bearings is not a huge issue. It took me a bout 3 hrs to change all the bearings on the Intense (bought it s/h) Cost £35. The S/C took less time, but the bearings (2 rather than 8) cost me £28 - some weird american size. Friends with Uzzis reckon bearings last 18mths + (same as the SC).
Cost isn't that unreasonable either compared to Intense, Ellsworth, Titus etc, particulary given its cutting edge technology.
If I hadn't picked up the Uzzi cheap, I'd probably have one on order...
