+1. I have a ‘66 Slim and a ‘79 Super Adjustable. They’re similar, but different. The Slim feels better in hand, but the SA is a bit smoother and more efficient. Definitely worth having both.All Gillette adjustables shave well. Of those I’ve used I would rank them:
1. Post ‘77 SuperAdjustable (“Black Beauty”); 2. Pre’ 77 SuperAdjustable; 3. Slim; 4. Fatboy. I’ve never shaved with a Toggle.
Stay with the Slim and pick up a SuperA. You won’t be disappointed
