LL, just my opinion, I don't think it is your axis rotation. I think for the right side it is break point & entry angle that causes better carry. On your side more hold creates longer skid, along with your side turn, hence later stronger backend move resulting in pinging 7's. I think you would be better off with a 10 o'clock even with finger line to get slightly earlier roll with a hint less backend. This should change the entry angle slightly & not drive quite so hard on the backend.
I'm not a Guru, but my opinion anyway.
