Before FBV, I was skating on 9/16. I read here that in general, 90/75 is similar to a 5/8 ROH and 100/50 is similar to a 1/2 ROH, which would put 9/16 between the two. I've been skating on a 90/75 FBV, which I like pretty well but might want a little more grip so am considering trying out 100/50 (and will likely do so next sharpening). But it got me thinking - I realize it is ultimately personal preference, but in general do people have a sense for where in between hollows such a 9/16 or 7/16 fit into the FBV world? Do people generally find that they need to go up to a less shallow "equivalent" hollow, or down to a "deeper" one? Are people on 9/16 generally more likely to like 90/75, or 100/50, or something else? Thanks.
