What is the best 12 o'clock bar, and why?

I'm thinking of getting a Powers Stuntworx one for my 2000 F4, but I am just going on looks and the fact that you don't have to drill the subframeb/c I don't really know which brand is the best...

 

powers where its at.
i want a round bar and they dont make it for my bike yet. so sick it will be when the time comes for a new bar.
powers **** is so strong man. i went down 60mph nose wheelie 12bar hit hard friends said. didnt move a bit. but my subframe bent and snapped like a twig

 

a 12 bar is a 12 bar. Its not like a cage where one design is going to be leaps and bounds above another. I have a freestyle inginuity on my bike, and it is just fine. Im about to shorten it up a little bit though.

That powers bar in the pic is rediculously long. That is a 636, and mine is an inch or 2 shorter and I still think its too long.

 

I agree, You can tell if a 12 bar is going to be junk. They are all damn near made of the same thickness and length of metal. Heres some advice. Dont by one that is make of cardboard. All the rest will be fine.
