As the title says - anyone have experience with both and noticed if one is hard on free hub bodies than others?
The PG990 has the largest 6 cogs on the aluminum carrier that spreads the loads nicely, but the the smallest three cogs are all individual and not much to prevent them from digging in.
The PG980 I think has 4 sprockets connect by a spider, another 4 connected by a smaller spider, and the smallest by itself. Less individually loose cogs, but maybe more pressure points?
