I had to proceed more gingerly as the front Raven isn't nearly as robust as the rear. I elected not to cut as many grooves as originally planned leaving the center for upright highway wear. I learned the blades should be changed often, with each tire I guess.
The new front tread pattern isn't exactly what I had in mind but I'm pleased. I consider the rear a success because there is no adventure touring tire on the market in that size. For the front though, I'll have the option to do this again or simply buy a 120/70 Distanzia or something. We'll see.
