Well, I use to do commercial two way. There are various sizes of hard
line, all the way from kind of small quarter inch flexible stuff up to 6
inch stuff used in broadcasting. Most of what I used was wither half inch
or seven eights. The half is fairly flexible, but you have to be careful
with it, kind of like making a bend in half inch refrigeration coper
tubing. It has a solid core and the shield is kind of corigated to make
it flex better. Takes special connecters which are a pain in the but to
install.
