Flex Duct vs. Straight Pipe

I am finishing my basement and am at the stage to add duct work from my main trunk line to heat the space. I was going to use 6" flex pipe but some of my runs are ~20' and someone told me to use straight pipe instead because I would lose too many CFMs. Should I be concerned about this. Since I've never done this before, that flex pipe looks so much easier for me to work with. Any thoughts?

Yes DONT use the flex. Get the round sheet metal pipe 6"X5' and use it. The flex has to much drag in it. you can put 2 or 3 of the pipes together on the ground with 3 screw in each then put them up. A lot easier to hang them up there than the flex anyway use just wire to hold them up. ED
