Might go back today. I told myself yesturday that 6 hours hunting this lot was enough but now i think I should give it another try. I went over it with my F75LTD2 and E-trac. Used Sinray x-5 coil, tornado on F75, Stock 5 inch on F75, Sharpshooter on E-trac, stock coil on E-trac. Don't have many coils left to use on this yard except the NEL big for F75 and Sharpshooter on F75. Might give them both a try there. THe French and Wheats were around 6 inches. SO, I bet the 1800 stuff must be around 8. I surely will find some 1800's stuff at a house from 1840.
