The Hardest Body Type to Deal With When Rolling With Someone

I think a lot of people would agree that one of the hardest body types to deal with is tall, long people. For you, personally speaking, what do you feel is your most difficult body type to deal with when you're rolling with someone in there? Is there a particular body type that you're just like, Oh man, this guy's going to be a pain in the ass now? Small guys, you know, like smaller than average guys. My biggest nightmare right that the guy I wouldn't want to go to right now is a giant slayer. If I have to, I'll work on it. Of course.
