Thanks guys, I'll go ahead and get an 8-way and give it a try.
Can I use the crimp type connectors without a special tool? I'm
seeing "compression type" which our cable company uses, and I don't
ahve one of those tools. I do have a simple solderless-terminal
crimper that may work to crimp type connectors.

Do they make one that works better than the crimp type, like one that I
can just screw together or something, there won't be much opportunity
to pull on these lines as they'll be in the wall.
