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
