I think a good way to look at it, would be to take the current crop to haney's day, so to speak, and then compare them to haney, they'd look like shit on mid 80s cycles and methods. IMO they'd get crushed by labrada, ray, gaspari, de mey, and obviously haney
Haney on todays stacks and ancillaries while possibly better than what we have, would still not be a pretty sight
However! Take haney or sergio to the mid/late 90s era, with what the guys were on, and let them emulate the look of the time, AND THEN we'd see something unbelievable!!!
