GP Supersonic (new version) vs Vittoria Corsa Speed on HED Jet+ rims

I know, I know, yet another tire thread...

I have the choice between the GP Supersonic (new version) and Vittoria Corsa Speed for an upcoming half ironman (Santa Rosa). I'm running a HED Jet+ 6/9 combo. Which tire combination do you think would be the fastest? The choices are both Supersonic, both Corsa, or a combo of the two (probably Supersonic front with Corsa rear). For reference, I'm an age grouper that plans to go for a 2:30-2:40 bike split.

You are splittings hair IMO. Both will be perfectly acceptable solutions IMO.

Cool, then Supersonic it is. That Corsa tire is a major pain to take on and off even with levers. Thanks.

I agree. I doubt there's a huge difference and both will be fast.

But yes, it would be great if we could get some data on how exactly the new Supersonic rolls.

Did someone hack Gerlach's account? Maybe Pubes? Splitting hairs over really fast tires (like checking manufacture date on Supersonics to get the really fast ones) is what we do here!

Put the Corsa on the rear. The Supersonics I tested were the new ones and they rolled quite slow. I don't trust Continental, so I never ride a tire of theirs that I haven't tested on the rollers first.

Where are you buying these tires? I don't see the corsa speed TLR anywhere and how do you know you're getting the "new" supersonics? Thanks :)

Supersonics from starbike.com: http://www.starbike.com/...ix-Supersonic-974-en

I know it's the new one because it is not completely smooth.

Yes, especially to get some numbers for how the new SS rolls compared to the old (most recent) SS ...
