As an instructor, I feel it's my duty as instructor to roll with every student regardless of skill, size, or strength. I've found myself at time rolling with guys that are pushing 260 - 280. I've heard of individuals and instructors a like not wanting to roll with individuals much larger than them. I like competing in open weight classes and I find that it helps my game a lot. It opens my eyes to different sized games. It forces me to develop certain aspects of my game that I wouldn't normally work on. I find it better for me and for my students. What's your take?
