         Hi Bill

         Congratulations on your award.
         Re the plugs. B9EV B10EV will give  about 75 hrs on 100/130 Avgas.(that is more lead than low lead 100)
         Tracy uses SD10A SD11A and gets 200hrs. SD's are expensive. I am trying          B9EVX  B10EVX platignum mainly because I could not get SD's soon enough. If you have coil or R suppressed leads don't use an R plug.
