Weight is overrated in my opinion. It is a factor for sure but training/experience, strength, endurance, speed, and personality are probably even bigger factors. I do enjoy taking on women who are significantly larger than me because not a lot of women my size can challenge me very well. There are exceptions of course but I have all the other factors in my favor most of the time. I do enjoy watching size contrast matches, really most any kind of contrast between different body types.
