I read in Flex magazine years ago that Haney was up to 259 pounds in pre-judging at one of his later Olympias. Unfortunately I cannot recall which one. Haney pushed the size envelope while maintaining the CLASSIC LOOK (v-shape and a TON of definition, with a TON of size).. Haney was one of the best. He was ahead of his time and NO ONE compared to him in the 80's in regards to size, with exception to Bertil Fox and Mike Christian. Lee Labrada was too small to be considered a threat. Gaspari was vastly overrated.
That being said, I think Yates's PEAK was 1993-1995 (competitive years) and was virtually unbeatable during those years, with exception to MAYBE a 1993 Flex Wheeler and 1994 Shawn Ray.
