Yes, I agree,  both units come in fairly light, I think.  I used a two
throat 4 injector TWM TB when I first started flying, but came to the
conclusion that the two 2" dia holes just did not create enough

velocity of

the mixture to stuff the chambers fully at 5000-6000 rpm.  Apparently

worked

fine for the guys turning 8000 and above in race cars.  It is

certainly a

nice, well made unit and for your 3 rotor will probably be just the

thing.

Onward to more (less weight that is) progress.

I chose the 44 mm diameter barrels, about 1 3/4".  Based on the drop in
manifold pressure at high rpm, I was thinking larger would be better.
But there are other factors, and until you can do a direct comparison,
same engine, same engine; preferably on a dyno, you don't know.

It takes about thirty milli microseconds to realize that ANY pressure drop
across a throttle body at ANY RPM reduces the HP :) I am stunned. You guys MUST
be kidding!!!
