You're saying you can weighted chinup bw+180x2? Last I tried I chinned bw+140x1. And dipped bw+120x3. I think most people can dip a lot more than they can chin though. I know Marvin Eder chinned bw+200x7 and dipped bw+400x7 and he didn't look very "imbalanced".
I think that's really interesting that you did that on a fruitarian diet. I've been vegan myself the last few years and it hasn't hurt me at all.
