I recently got a Shavemac with the DO1 knot. The backbone isn't a problem, but I do find it is too scritchy scratchy for me (moreso than boar). I'm wondering if anyone who owns both the DO1 and the regular 2 band can comment on how much softer the 2 band is? So far I'm leaning on solely switching to synthetics, and I'm not sure if it's worth it to spend so much again on another badger? I've heard that some badger knots are treated with gel tips? Not sure if I remember which brands... maybe SV, Declaration Grooming? That might be a path to explore?
