And you're right, I'm not nearly to that stage. That will be if I decide to upgrade pumps and what not, and go to 1100lb bags. I'm assuming most people that go to 1100lb bags upgrade their pumps? It would take a long time to fill up that big of a bag it seems. It just sounds like for my purposes it's better to find some less expensive used bags right now, and maybe down the road I'll go 1100 if I feel it's necessary. If I end up buying new though, I don't see why I wouldn't just spend the extra $80 and get the 1100s now.
