Oversimplification on my part. I guess for most ops this might apply.
I have a high and low antenna for that reason. You're right.

The 617-6B is a very old design. If you look at the manual is is dated
9/91. It was designed before antennas were computer modeled. More boom
usually means more gain *IF* you have enough elements to produce that
gain. At 33 feet plus of boom the 617-6B needed another element. There
are one or two newer designs for the 617-6B out on the internet that
include a 7th element.
If you believe modeling, which I do, the 6M7 is indeed a better
antenna. Both gain wise and front to back. IMO it is no contest unless
you want to mod the 617-6B with an extra element. The 6M7 is a better
antenna than the stock 617-6B and has about 2/3 the wind load.
As for 6m Es being either open or closed and any antenna will work I
beg to differ.

Just like any band or mode you can do things with gain that are not
possible otherwise.
