It really all depends on how tall you are, were you comfortable with the stock height bars, do you like the taller bars????
There are a lot varibles, because it could either ruin a ride or make it awsome. I'm 5'6" and didn't perticularly care for the stock height and bend, my arms would get tired faster, I wanted a bar thats lower, so I went with a dirtbike bar and got the MSR CR highbend bars. They made me way more agressive at riding, the quad is easier to steer and turns on a dime now, I tire just as fast but that because I'm riding a lot faster and harder.
