Yes I know this has been done to death on here. Ive read most of the links on the FAQ thread and have decided Im going to take the plunge and use Cat 5 (for the fronts at least). However, I have one question that the existing threads dont seem to have covered: How large and flexible (or not) does this stuff end up? Assuming I use 3 runs of Cat 5 for each channel pleated Im guessing Im going to end up with something at least 20mm diameter and quite rigid? Thats a pretty chunky unwieldy cable to route around the room. Since Im in an apartment with concrete floors and ceilings and breezeblock walls chasing a 20mm dia cable is going to be a hell of a job. How easy is this stuff to route?
