Hi All,
i've been using and honeing straight razors for about 2 years now. I would say that my skill level is on the newbie-side of intermediate. I have 4 blades (dovo, TI, gold $, and a vintage robson) and my honing setup consists of a dmt 120 for lapping, norton 1k, 4k, 8k, naniwa 12k superstone, and zulu grey natural stone finisher.

2 of my razors hone and shave brilliantly; 2 are acceptable shavers and tricky to hone... they certainly pass the hht and other tests of bevel setting and sharpness... but they are not as great as my other two. These two razors (TI and gold $) have a slight wrap. i would ink the cutting edge and find that i was not cutting steal on heal/toe of one side of the blade. I tried to solve this problem by adding one or two layers of tape and doing rolling x's.

Yesterday, i stumbled upon this youtube video by @drmatt357

the video recommends checking the flatness of the razor using a granite or glass surface and seeing if the blade wobbles. Sure enough, the difficult razors were obviously not flat - i can tap the corners of the blade and get the razor to wabble. Not surprised because the ink test showed that the blade was not true flat.

In the video, drmatt357 recommends honing the warped blade down on a stone or dmt plate. This represents a departure from the typical advice i generally got. Normally folks deal with warped blades by compensating for the warp using rolling x-strokes.

so - after this long winded intro; here is the question...
when we have a warped razor, is it better to simply correct the warp by removing metal from spine edge until its flat, or is it better to simply live with the warp and compensate for it using the rolling x.

I like the simplicity of the 'grinding it flat' solution, but i am worried that by doing so, i would somehow alter the geometry of the edge (i.e. go from straight edge to a smiling or frowning edge).

Obviously, the grinding correction will introduce spine wear, but that is something that i don't care about with these razors.

Thanks for your thoughts and advice.
