I love my 2-Strokes but I start feeling like the designers need to do a little "catching up" when I see Saito .82 and 100's in the same weight class as 2-Strokes half their displacement. Brodak has a non throttle .40 at 6.7 ounces the listing says it comes with a muffler but doesn't specify if it is included in the 6.7 ounces. Saito's advantage in weight is due in large part to their AAC design also. Why don't we see AAC 2-Strokes of 1.25 displacement in the 20 ounce range? O.S. is among the lightest that I know of with the 1.20 AX just over 31 ounces. That makes it heavier than a Saito 1.80.
