Which impeller will work best?

[andrewthomz77]

I have purchased a new wear ring, new gaskets, and now looking to get the correct impeller. I have a 2012 RxpX 260 ... but when I search for it on Riva it gives me 5 different options. Just looking for the best advice on which one i should go with, and what the difference of them are if anyone knows?
Thanks in advance, safe riding
