The NEWs are fine shavers and I recently purchased a shaver grade Senator here on B&B, in part because I have recently rediscovered open combs. I have to say, based on two shaves so far, the Senator is a tad more aggressive than the NEW and I found myself slowing down a bit to avoid harm. I'm sure most of this is getting used to its geometry and blade angle and in the end I got a very nice shave without irritation.
If you like NEWs, I think you'll be very happy with a Senator.
Got one a few months ago. It was for sale at $5 USD and I still thought of not buying it. The reason, I found open comb razors were to aggressive for my face. But this Senator was in great condition and I wanted a razor that would deal with a two-three day growth. Glad I bought it. Using a Feathers blade it cut down my beard without nicks or weepers.
I don't use it as a daily shaver but for the mentioned situations.
