Yes, I would be careful. Someone who is significantly heavier than yourself has several advantages:
1) his punches will be more powerful;
2) the mechanical energy tranfer from his fist to your head will be more efficient;
3) he will be able to take up your punches much easier.

As a musical term for sure, "the '80s" imply the late '70s and early '90s. You can think of them as tapers of this golden decade.
