10' 1 1/4" pipes are like 7.50 CAD at home depot. i bought some the other day. they have 12' lengths at some stores too. if your scared about it shaddering see if you can find some schedule 80 pipe at a plumbing wholesale or something. but for the most part if you dont build your rail properly or if you use a big diameter pipe it might break. and dont confuse pvc with the black abs pipe because that will shatter in the winter.
