I'm running Crossmark LUST and they're fairly good. They roll fast and yet still give a relatively good grip on the dirt.
The Ranchero's are good. They roll fast, however they're not the grippiest tyre. Although on an upside for that, you get to know pretty quickly when it's about to start drifting and how to avoid it.
The Ignitors are good tyres if you want a grippy tyre that rolls relatively well. Although it wouldn't be as good as a Ranchero or Crossmark in rolling, it'll grip slightly better. I'd only suggest an Ignitor on the front.
From my experience Michelin XCR Dry's are fantastic tyres. They roll fast and grip pretty well too. Although the knobs aren't as big as an ignitor, it's still comparable. If you want something really racey
Go Michelin XCR Dry 2's. Ever only ridden on them once, but geez it gripped well and rolled bloody fast. Don't expect it to last though.
For an overall, grippy, fast rolling and yet durable combination, i'd suggest an Ignitor on the front and a Ranchero on the rear. Fast rolling, yet the combination of an Ignitor up the front gives you the confidence in the corners, and the Ranchero keeps the rolling momentum up.
Stan's works fine with any Maxxis tyres in my experience.
