Hi Mike, and welcome to Simply!...I don't have them...but the two books by Andrew Soh are supposed to be very good. I believe the first one is call Discus: The naked truth, and I think the other one is call Problems and solutions. Might be enough for you to get a search going. I am sure others will hopefully chime in and be more accurate...Tho stick around and search the sight as there is a boatload of up to date info here, which I prefer over written material...Bill
