DC04 Green & Lime will fade like an utter bastard, just sell it! £40/£50 if it's nice and clean on facebook, cash in your hand!
DC14 Origin - Keep! I much prefer them over the clutched, their just so much better at grooming deep down! Ideal daily! (or £50 on fb etc)
DC33 - Possibly keep, not really worth much more than a 14 in the real world, because no one cares that it's newer etc. At that stage where the ones left are in either good condition or utterly trashed, probably worth keeping it
DC07 - What colour scheme is it?
