Do a run at 70 lbs. and a run at 140 lbs. to make it simple. The difference is quite astonishing.
I snipped to make it clear that in one sentence you say that pros don't use wide tires and then in another pointed out that pros do use wide tires.
As for tire performance on rollers, I just don't care. I haven't ridden a roller race in 25 years. In the real world, on the roads I actually ride, I can use wider tires with no performance penalty while enjoying increased comfort over narrower tires.
