Nobby Nic Evo 2011 alternatives

Hi.
After my NN Pacestar 2.1 blew up http://www.bikeradar.com/forum/viewtopic.php?t=12792905
now I'm after a similar tyre, but with better NoTubes Crest compatibility.
I'm considering
NN Evo 2.1 2010
Continental X-King Supersonic 2.0
Any other tyres I should have a look at? Thanks.

+ some other bikes.
I wonder if there are any problems fitting Conti tyres to the Crest rims.
