what 1515 1y or 2d for 6s

[theJoker]

I am going to run this motor in the eRevo when it comes out and in my 1/8 buggy until I get the eRevo.

I think that I want to run 6s it would be nice to be able to try 4s as well.

so is the 1y 2200 rpm/v to high for 6s?? would the 2d 2050 rpm/v be better or is the 150rpm not going to make a big diff ...

Thanks
