I've got to disagree with most of you on this one. 

Years ago we used net keystones for our phones but had to service a few (not many) due to the phone cord moving and shifting and shorting out the pins which killed the phones.  With how little phone jacks actually go into houses today, I don't mind carrying a few extra keystones.

In 12 years I've changed only a handful of RJ11 keystones to RJ45's so pulling out a few tools is no big deal.  12 years of not having to punch down the green and brown pair should make up for that time=)

Also, we try not to plate any feeds that will be used for baluns, especially HDMI for obvious reasons.
