Hi Dave, if it was good enough for the likes of Colcord, Whall, Doerflinger, Abrahams, Shay, Hugill, Terry, Bone, Bullen, Harlow, Nordhoff, & others (as well as those here) to discuss this topic & more it's fine enough for the likes of little ol me. And it's not all book larnin either some of it comes from under the belt & being under sail not to mention being under the gun. Sing & sail away but hell talk it up too. Barry
