I am looking into getting a new short shifter and the one i currently have a a single bend version. Looking at the other shifter avaliable i noticed that there also avaliable in a dual bend and straight no bend design. How will these other two design change the position in relation to the singe bend that i have already.

 

The dual bend should be a little closer to you... while the straight one will be a little further away [and the **** will be low as hell]
I have a B&M straight.
