I had both the Griplink and Powerlink glued up on my wheels and at sale price ($90 a set) its a pretty solid deal, but I would rather go with some Vittorias. I probably did around 2000 miles with the Mavics and they did a decent job. I did flat both the Powerlink and the Griplink within the first 100 miles of usage (a staple and a small thorn) but Stan's sealed it up (the valve cores on these are easily removable which makes using sealant on the road rather simple) and I was able to continue using the tires (they even stayed properly inflated). After 2000 miles I finally had to toss both tires as they would no longer hold pressure because I had amassed countless other cuts and small holes on them. At that point they still probably had 500 miles of life in them. As for the ride and grip - decent, but nothing special, there are better tubulars out there but if you can pick these up for half price I would go for it.
