Mine is just shy of 30lb (XL) with Deore chainset, Avid Juicy 3s, Fox Float R (never had any problems with it here and always felt good), Fox TALAS 32, Thomson stem and post, Mavic Crossmax Enduro wheelset. Could probably go a wee bit lighter but that sort of stuff doesn't interest me.
If I was buying again I would probably spend the extra £130 for the RP23 then the bike would be future proofed if you know what I mean, £130 spent now is £170 saved later on when you've got an itchy mouse finger.
