Pro Tank II vs Davide vs Aro

[caged]

Has anyone tried all of these (Pro tank II, Davide, Aro)? Which one has the best juice flow without flooding? Capacity isn't a huge issue for me, but being able to crank up the watts and avoiding dry hits is. The Pro tank II is awesome when I can get to 8.5 to 9 watts, but I've only had one head that can do that.
