Sns, I am just curious. If you have the following suspect issues:: 1. Cart alignment / 2. inadequate Cart / 3. Remaining stock caps / 4. lack of break in of new caps..
How could you ascribe anything to a particular alteration?
IMO, you need to come up with a systemic approach. I don't change but one thing at a time and than wait. The shotgun approach is very confusing.
