mob is 60 grit tape. jessup, iron horse, black magic are 80 grit. Im a 80 grit guy myself but if i wanted 60 grit i would choose madrid flypaper over mob, gotta love the sparkle to it. I really like mini logo grip too as its a mix of 70 & 80 grit or something along those lines. I wonder what grit this company is going with.
