James, on the next run, try setting the LS needle with the HS needle at full peak. If not you'll end up chasing the needle settings all over the place. The HS needle seat is fixed, so setting it at peak eliminates one variable. Someone mentioned that one of the knocks on the .65 is it's weight, on the other side of that coin is it's smoothness due to it's weight and lower power.
