Quote: The good :Its running smoother, feels much snappier, feels like its pulling harder and smells cleaner
The bad: I should have done this sooner
The unknown: taking it to the track Saturday and see how it does straight from Thumper. A 2 tenths increase will put me in the 9.80s and I think it could happen.
just keep in mind the air is a lot different now than it was when you last ran. it's not uncommon to gain a bunch from summer to winter. hope you get it but not a good comparison.
