They are so close, I'd say decide based on tread not width, since the casing is likely the same size. I have both which I swap out as needed on the front. The BG is great for hardpack to medium-loose, the Nev is great for loose conditions. Both work on wet rocks/roots.DM-SC said:Edited because I can't read Shiggy's site!
It appears that the BG is a smidge wider than the Nev.
