Yes this is true...to be honest I'm not a fan of 80/20 for its weight reasons(even though my team used it with out problems this year. We didn't make our whole frame out of it though, we only used it for crosses)...
80/20 is unneccessary if your team CADs well, because you can plan all of your cuts ahead of time. 80/20 can be nice if your team likes to make it up as you go and constantly be taking off and adding parts. (not that you can't do it with other materials, just 80/20 makes it easy).
I would still recommend it for a prototype though.
