Was reading the thread about the guy rolling with the bigger, stronger guy. I have the opposite experience in my gym sometimes. I am 5'10", around 200lbs. Used to do a lot of weight lifting, in fact I started BJJ at 235lbs, and have dropped all the weight for MMA (plan on going to 185lbs). Lately, with the summer weather and all, the classes have been very small. Usually its me and few smaller guys, 150lbs or so, all white belts. It's difficult to not take advantage of the size difference, especially when the smaller guy is going balls out trying to sub me, and I can easily overpower him or counter. I am not great in BJJ, only been here 3 months, but just shedding some light from the other side of the mat. I feel stupid when I hold back, but at the same time, I'm sure it's no fun for the smaller guy to be completely smothered by me all the time. I can't wait for summer to end and the rest of the guys to come back.
