I was considering that beam too, until I realized that
it has less than 1 dB of gain* over a 4 element SteppIR that
covers all those other bands.  The boom length of those
beams is in a region where gain increases at a relatively
slow rate vs boom length.  Also, the KLM boom is rather short
for 5 elements, so you don't really get much gain advantage
out of the extra element.  The boom is shorter (in wl) than
the 4 element 10 meter beam that M2 sells.
