I don't have one but I have heard several with both the 3 and 4 el versions.
One, K7SS, has the 4 el with the two extra 6 meter elements. He was loud on
6 and I am all the way across the continent from him.

W1NA has stacked the beams There are now several others...

Sounds like a winner to me especially if you want one antenna for 20 to 10
plus 6.
