best aftermarket bars?

Check out Suburban Machinery on the net, I have just purchased a set for my FZ6, nicely made but a little on the pricey side.

I had a set of renthals on my old FZ6 and really liked them. You just have to get used to the angle of them at first but after that they were a lot more comfortable than the stock. I am 6'2 and have monkey-like arms, so it helped out in the comfort of the bike.
