Would love to see the Bonty R4 aero.
Al has tested that one. http://www.biketechreview.com/...ire_testing_rev9.pdf
It does very well... and is purported to have very good aero properties of course. Don't know about the durability and puncture resistance. It appears to be based on the Vittoria Diamonte which isn't noted for durability, but it's likely as good as a Supersonic.
If you send me one of your tires I'll test it... a used one preferably (else I'll have to break it in for you), but not used up.
Speaking of Vittorias, they make a track tire based on the Diamonte with thinner tread and no anti-puncture belt. I thought about giving one of those a try... but then decided it was a little too extreme even for me, to actually use in a race.
