My LBS gave me a good deal on them, but I guess they would have given me a deal on the s-works too. I had been thinking about trying out the S-works but I figure that for the couple grams I'll go with the tried and true closures. That said the S-Works are supposed to be amazing too, I believe the fits soles etc are essentially identical and it's down to closure and weight.
I'm excited to try them on the road. Did a little riding on the trainer in a test pair but because I wanted 2010s I had to order them in.
