Interesting thread - your lucky to be able to cable your own house (self build?), trying to move at the moment, and negotiating with builder to get some extra drops put in, I think they are using someone like the queen to install it based on the labour rate that must be required to run 10m of coax and fit a plate!

Also CAT6 has to be installed in a particular way or you will get lower quality than cat5 apparently.
All cat cable has to be terminated cleanly at each end, the problem comes when you untwist the pairs too far from the termination and you get noise/interference. You want the pair to be twisted until the very last minute before it goes into the patch panel or wall plate.
Never heard of cat6 being any more susceptible to this than cat5, other than the toelrances may be a bit tighter due to the higher speeds supported.
