As a do-it-all rim I'd go for Mavic EN321s (or are they EX321s?). I've had a set on Hope Pro2 hubs that have been on my hardcore hardtail for ever. They're solid, but not so heavy that you can't ride XC on them. Got mine from Merlin 5 years ago and they haven't even needed trued in that time!
May not have street cred with the yoofs though*
*I have no idea what is considered cool these days.
Is that on your Rumble? The reason I ask is that I have exactly the same wheelset on my Rumble... which was bought from Merlin 5 years ago!! And mine have been perfect too!
