I can't pick one. But I could narrow it down to the 3 that I appreciated for the longest period of time, they do overlap and were from the same period:
Annie Rivieccio
Christine Envall
Marja Lehtonen
They all had the full package. Arms, chest, back, quads, calves. Annie and Christine's most muscular would send me wild. Marja had the size. They also didn't get implants, although Marja did towards the end of her career but was without for most of it.
Paula was amazing. One of the best and biggest upper bodies ever.
