@nzandyb: Some people just aren't skilled or aggressive riders and/or their terrain is really tame. Nothing wrong with that, and for those people, super light and fast tires can work. For more aggressive riders and/or more severe terrain, we have to accept as much weight and rolling resistance as necessary for our tires to survive and to be able to enjoy riding as hard as we want. I'm currently testing tires all the way at the light end of the spectrum. They're faster overall on most terrain (within their appropriate range), but the need to back off on descents and be vigilant for sharp rocks takes the fun out of the experience for me. Still, there exists a use case for them.

Hey now, it's only f3.2 ... at 1/1000s ...

Agreed. Until then, I've found the Rekon rolls as well as the Ikon and has a little more traction.

Testing by [L=https://www.bicyclerollingresistance.com/mtb-reviews]Bicycle Rolling Resistance[/L] suggests that although Super Race casing is heavier than Liteskin, it has similar rolling resistance with about 33% better puncture resistance - assuming the puncture test protocol is a good analogy for pinch punctures. The BRR test protocol isn't a perfect representation of actual riding, but it's the best public data I'm aware of. The increase in total system weight is approximately 0.2% - 0.35%, mainly depending on the weight of the rider. Even factoring in the greater significance of mass at the perimeter of the wheels, that seems a fair trade for increased puncture protection. An extremely light rider may have less need for puncture protection and would benefit more from the reduced weight of Liteskin - or maybe a variant of Super Race without the central anti-puncture strip. That's a small share of the market, though, so I don't blame Schwalbe for reducing their SKU count - and I wouldn't be surprised if they offer pro-only versions for the lightest riders or smoothest courses.

Home mechanic, yes, but if I charged by the hour and saw a particularly expensive and complex bike roll through my door, I wouldn't call that a bad day.
