well, maybe I wasn't being quite honest My comp bike weighs around 10kg, thats with some super light parts (ti bb, pedals axles trialtech sl rims ect) but also some heavier stuff too (rain king rear tyre, 200mm rotor, vee brake with adaptor and booster). However, my street bike weighs 11.5kg with no light weight parts and a saddle, but I have now taken the brakes off and fitted some lighter tyres and its now around 10.3kg. Stick with the heavier weight for now, but if you do comps next year, you could put some lighter parts on before them.
