Topband: Using a DX-Engineering 80m vertical as part of an inverted L on 160?

[WA8JXM]

I am wondering if anyone has used a DX-Engineering 80m vertical as the vertical part and the support for a 160m inverted L, connecting the rest of the required length to the top.

Of course there would have to be one or two guys to counteract the pull of the horizontal part of the L.    Seems like a reasonable way of getting a 65' vertical support.

On a related note, how much real difference would a 65' vertical section make vs a 40' one (total radiator length being the same?)

Although an eighth wave vertical portion seems like it would be worthwhile, I have to wonder if in the real world it would make a significant difference vs. a 40' vertical section.

Tnx,
