See my main interest in this razor is comparing it to my 34c and i've never used a slant before.The whole reason I sold my 37c was it just wasn't different enough to my 34c. Didn't get noticeably better shaves with the 37c. 34c now doesn't get used since I bought the progress. if the chance of using a fasan or a German vintage bakelite slant came up my mind may be changed but right now I'm pretty sure the slants are a bit of a gimmick. As always however, YMMV.
