[TowerTalk] Mixing Rohn 20G and 25G

[Linux Mercedes]

Hello,

Whilst moving tower sections from the shed to the shop so I could clean 
them up and make a couple of fixes before putting up my tower, I noticed 
that some of them seemed lighter than others. Turns out I've got a mix 
of 20G and 25G sections.

What are your thoughts on putting up, say, 30 or 40 feet of 25G and then 
another 20 or 10 feet of 20G? I'd like to use the best sections I have 
on the tower, but if mixing is a no, then I'll fix up some of the other 
sections I have and build a homogeneous tower.

Thanks,
Nathan
