I got a pair of the vapour laces last year and they're now on their way out. They're the first Scarpa shoes I've tried, having worn mostly anasazi greens and velcros (plus one brief flirtation with Miura laces) for a few years...
I found them very precise and comfortable from the start; they have stretched over time, but not by a huge amount (less than half a size?) and whilst they're quite stiff to begin with, they rapidly become a great smearing shoe like the anasazi verde. I thought the Scarpa heel was a better fit too. The build quality seemed vastly superior to any pair of 5.10's that I've owned. So all said, I liked them alot.
One point on the sizing: I've always found that verdes are a better fit than velcros for me, whereas pinks/whites are far too low volume. The vapours definitely have more volume around the toes than anasazi velcros - so, if you're considering the anasazi lv because you have narrow feet, you might find these a bit too roomy around the toes..?
Oh... I thought the rubber was pretty good - it's the same as Sportiva are currently using - no real difference in performance to Stealth rubber in my experience (but then, I'm a total punter, so it'd probably be lost on me anyway)
Hope this helps
