Hello there and happy weekend to you all.
I recently acquired a Merkur 37c slant and have shaved with it everyday for the past month and have quite enjoyed the smooth shave with fewer passes compared to other closed-comb razors I've tried.
I started checking out Gillette New heads (both long and short combs), particularly those offered on the Bull Mastiff handle (I do like the regular handle over the deluxe handle). I've gathered from some that the New OC may compare favorably with the slant and have longer blade life. I've read some feel the short combs are either very similar to long combs, slightly more aggressive or just easier to wield in certain areas (i.e. mustache under the nose).
Stick with the Slant and live happily ever after? Try a BRW -- short or long combs? Different option altogether?
