Which Schick Injector (or modern equivalent) for someone who likes efficient razors?

Get one that can use a Schick Twin, such as the M, although other models can accept a Twin Blade. (I know L models can, not sure how far back you can go, and have the Twin fit properly). The Twin blades shave super close, up there with an R41, yet without the risk of blood, and very comfortably. - My M Adjustable and a Schick-Twin gives an awesome shave.

I have an E-2, a G-4, 2 I’s, 1 is a hydro-matic, a N-1 and an O clone. I prefer the N, G, and I. The E2 is a little too aggressive for my taste.
