Thanks for the information. I guess the next thing to try is one more spring notch on the one rubber/one Curvetine rows.

I would really appreciate it if you would take one end row and put two on as I suggested above. This 2-Curvetine row MAY use one less notch on the spring than the others. Then compare the emergence to the row with no Curvetines and the rows with one CT + one rubber.

Thanks again.
