Hey Joe, you may want to try to Sensor Excel blades. They are trips and give me, at least, a real close shave, plus you can use them with the headblade adapter. I only need the sensor handle then for tough spots like around the ears. Two razors, but just one blade needed.
Joe, don't know whether the double Sensor's fit or not as I only use the trips. BTW, I get a long life out of the HB blades, too. And like you find that the later shaves are better than the first. Anyone else experience this?
I use Shick Extreme 3 disposable in the shower. Works great curves to the shape of your head
