It makes sense what you are saying. In the early 70's everyone was still clamouring over the brand new deca and dbol that came around in the 60's. It was the shit...you know how fads go especially around BB and gyms. Test was old school and poo pooed by the 70's. The fact is that the first test was produced in Europe and it was test E.So as you look at the Steve Reeves type body and watch it evolve into the Arnold body then you can see the difference that dbol made. And yes..you are correct...many BB's from the late 60's into the early 70's did deca/dbol cycles. They did grow big except a few of them were getting no wood.
After Arnold talked to steeve reeves and also one of the old Hoffman boys named john grimmek, a noted big testE user, he found that they never had woody problems. So you can thank Arnold for being the ever so curious one who remembered when he was 20 and taking testE and yet no wood problems. So they said let's try some old school along with new school. They went to deca/dbol/testE and for sure...they got wood and then got even bigger. By this time the USA began making test, but thought cyp would be better. As BB went along to the late 70's and early 80's no one wanted to use cyp...why you ask??? Because Arnold used E.!!! Of course he used E...it was all he ever heard of coming up in Austria. He used E because it was familiar to him and cyp was not.
These are the things I learned growing beside my drb's knee. Not a normal upbringing I know, but that was how our family rolled.
