I put zoo bars on my python - as they are risers, if angled forward they will give better reach over the front of the bike, making the bike feel a bit longer.
The Zoo bars are also angled back : which can put some people off - but if they are set-up correctly they can feel quite good.
i would'nt bother changing unless there is something wrong with your echos not worth wasting £30! (Y)
hope this helps
