I am looking to purchase a new MBP (when they release the refresh) and the new TC. What cabling should I buy to keep the Gigabit network? I was looking into the Cat6 and Cat6a standards, but have read both good and bad on STP and UTP cabling. Does anyone have suggestions to go either way on this setup? I have heard that some STP cabling the shielding slows the signal and of course UTP doesn't protect from crosstalk. Main purpose is to keep up the speed and of course minimize crosstalk and or lost packets. Any suggestions?
