well hehe a lava ball to the head is a bit crazy indeed hehe,but then again lets say luffy for exmaple in second gear controling haki,i dont see any way for akaino to give him a lava ball and even if he try he wont be able to make it.
so if u have a good df power plus haki and u know how to fight the way luffy does or mihawk,more chances u will defeat an admiral no?
Well yeah it becomes a fair fight then. If you look at the jet gatling that Luffy did to Smoker in this chapter, it looked pretty damn brutal. If he had haki on his punches then Smoker would most likely be almost finished. But I doubt it would be so easy against one of the admirals, they are no doubt faster, better fighters and their element is a lot more destructive than smoke. Enel might be a nice example here. Not only could Luffy hit Enel (like with haki) but he was also immune to his attacks, and still he had so much problems. Imagine how badly he would have gotten owned if the lightning could hit him :X. And rubber won't protect against ice, lava or lasers. But still, he can hit them, so it'll be a fight atleast :)
@YonkouSword:
How does Smoker go Logia and smokey if he is holding that
i could understand if you had to touch the stone to make it take you power away but if it releases waves then why doesn't it effect smoker?
also he touches it in smoke form all the time i don't think he should be able to use something that stops DF powers in a DF logia mode.

top left panel, he just holds it with the smoke, it is only the tip that is seastone. (what he presses against Luffy's neck)
