I have modeled some OptiBeam antennas and the published specs seem accurate.
Of course getting 2db more gain from the same boom length would circumvent
the laws of physics. I recently installed a 4el 40m OptiBeam on my tower,
the SP6GXP version is 37% lighter.

His 16 element 20/15/10 tribander looks like an almost complete copy of
my Optibeam OB16-3, except that SP6GXP claims about 2 db more gain on
each band and uses lighter weight materials.
