In reply to Morgan Woods:
alright Morgs?
I have just bought my second mammut Infinity, my girlfriend has the Revelation. My first Infinity lasted approx 4.5 years of fairly intense sport climbing, has been chopped twice in that time, and to be honest is still in reasonably good nick apart from only being 60m long now. A little bit of sheath slippage in middle of rope is only real complaint.
Having used the Revelation (which is a lovely rope don't get me wrong) I was happy enough to buy another Infinity on the basis of it being a bit more hard wearing albeit slightly heavier, and in my opinion slightly better suited to being a redpointing workhorse.
The Revelation is a joy to handle but the one bad thing I will say about it, is it loves to get snagged when pulling it down. You can bet that if there is a flake or crack or something it can get wedged behind, it will get stuck there. I wouldn't take it on something with a multi abseil descent for that reason.
YMMV of course.
