Well this goes back to my question of how are we defining “easiest”? Sure, if we’re defining it as how hard it would be for someone else to beat the top 1 or 2 guys, sure I’ll admit it’s probably 125.
But 125 is super deep. 133 for example has 3 studs (I’m counting Crookham), 3 or 4 pretty good guys, then kinda drops off a cliff. In fact the 4/5/6 guys (Nagao, Orine and Latona, I’m counting Crookham as #3, silly for Intermat to have him as #5 IMO), all have losses to 3 different guys currently in the 125 field.
