Don't know. 3.05 seems a little big. Let's see...PLA coefficient of thermal expansion is .0007, so a 70C rise over ambient is 3.05 + (3.05 * .0007 * 70) = 3.199. The E3Dv6 bore is 3.2mm, so that sounds like it's getting pretty close.
I'm not quite sure how the PLA really behaves once it gets up in the 90C range. It continues to swell, but it's past its glass transition temperature, so I'm not sure what happens.
You might try taming the stringing by tuning your retraction settings. I don't have any experience with the E3Dv6, so I'm not sure of the details.
