imho, 120 foot of 25g may be cost effective today but full of regret down the road, unless youre meticulous about inspecting and building to rohn spec. theyre super easy to twist, very prone to the bolt holes wallowing out, and if your drainage isnt right, they love to have blowouts. dont skimp on the guy brackets and just loop the leg, thats effectively installing a saw. im personally terrified of 25g over 50 foot, its so cheap people skimp on both upfront build and maintenance. I know this, i put in enough of them incorrectly before i knew better. there are margins in the spec, but thats for your safety. calculate out the value of the farmland you lose over the anticipated life of the tower, you might find you have alot more budget for an appropriate self supporter
