Topband: resonating Rohn tower on 160m

I have a rather a lot of Rohn 45 tower sections in storage (from my old M/M station in Colorado) and am thinking about using it in lieu of new Rohn 25 for the 160m 4-square I'm building in Vermont.

Thanks to all those who informed me that 126.5' of Rohn 25 in a four square will resonate @ 1.830-MHz.  How about Rohn 45, where does the assembled Top Band wizardry think it will resonate?  At a lower height, I'm sure, but how much lower?
