Not exactly lines, but these groups were pretty good:
94 spine: Lyon, Schwarz, Stynes, Neitz, Wight
94 half back line: Prymke, Neitz, B. Lovett
94 forward line that contained: Schwarz, Lyon, Charles, Lovell, Pike (all at their best)
98 forward line that contained: Lyon, Neitz, Schwarz, Farmer, Robertson and a resting Jeff White.
The 98 side was the best Melbourne side I've ever seen. I was too young to remember the late 80s early 90s though.
