Rear bumper

Have a question that will turn into a debate but anyways here it goes....
Which would you run a small rear bumper or a larger hoop type?
1.Small bumper not as safe as larger but someone wont want to tend to bump out of the way as much and will race ya a little cleaner.
2.Larger hoop style a lot safer but has a bigger area for the driver behind you to do the bump and run.
3.Will the change of bumpers change the handling of the kart?
So lets here it.
small. I don't think more races look at what bumper you have if they want you out of the way they will try there best to do that (without getting you to mad) lol. I am going to start looking for racers with hoop bumper to my advantage for the reason you gave. id image bumpers not change handling
