I am guessing you guys don't like the foam filled?
I'm not a huge fan. Badger claims there 5wrap retains even better.
I get interested in it from time to time, had a salesman spend 3 hours workin me over to start using logstor, the numbers he showed me werent as good as the 5 wrap and my cost was over double the 5 wrap.
The real success story with foam filled is the marketing machine central boiler, they can make anything sound great. However both pipe can fail if it gets a leak, that's why proper installation to me is wayyyyy more important than choosing between 2 quality lines. Someone said if the logstor gets a hole on it you can't hardly get it out of the ditch because it soaks up so much water
