I have 3 of these G1000, two black handle, and one blue handle. The black and the blue handled versions don't have exactly the same head geometry. there is a slight difference, though I can't notice any difference during shaving. The blue handle has a head exactly like a 70-s black handle superspeed. The problem is the handle of the G1000 is not that good as the superspeed. Grip could be better. Also the plastic handle makes the razor top-heavy. I really think this one is a wonderful shaver and a better one than a Tech. Very mild razor, that needs extremely sharp blades. Having tried more than 25 different blades in it, I must say that very few work well, the Astra Superior Platinum is The Blade made for this razor [and 70-s SS of course]. Try this combination. It's the perfect shave.
