Just read this post... wasn't heatwave reported to have a "90-95" bw in the beginning? I guess somehow that grew over the course of the past few years!
It is hard to judge a bull on just a few calves.... or in my opinion, a year worth of calves. Heatwave is great due to the HUGE number of cows he is bred to every year, and the type of cows (the best) he is bred to. Not saying he doesn't throw them good, but the odds are stacked in his favor by the shear numbers he is bred to.
It will be interesting to see what the next "great one is". Think it will take a few years to finally "discover" them, when they are right under our nose now!!
