Yasi is at the Red, but I asked her the same question this weekend. She uses Yosemite Bum and Sportiva rubber and they do a great job. I'm beyond thrilled with my Miuras so I will probably stick with the Sportiva rubber when it's time for a resole, even though I know 5.10 rubber is stickier. These shoes are the absolute shiznit as is. I also wonder if 5.10 rubber wears out faster?
I've used Flyin Brian twice on my Mistrals and have been real pleased. Quick turn-around time and the soles looked like they were new out of the box. My experience with 5.10 rubber is that it does wear out quicker. Stickier rubber is going to be softer, therefore it's worn much quicker.
