Re: tool-less vs. punch-down CAT jacks + cables Keystones are meant to be used with solid wire. Most patch cables are not solid wire, but are stranded instead.
I personally don't like the tool-less jacks. The time they save by not using a punch tool is wasted by half of them failing to punch enough to make a solid connection with the teeth in the jack.
You should use the proper jacks for your cable. Standard Cat5e is 24awg, while standard Cat6 is 22awg. You can probably get away with cramming Cat6 wire into a cat5e keystone if your not needing the rated capacity of a pure Cat6 network. Punching Cat5e wire down into a Cat6 keystone can result in loose terminations if the keystones are rated for such, which will cause network issues.
