Good answer FBM
but a valid point Billiebob. I know LASORS is already distilled from other publications but I still find all these little ins and outs confusing and difficult to access easily. There must be an opportunity for some web wizard to come up with a site that enables you to put in a straight question and get a straight (correct) answer. Wishful thinking though, given the fact that even the Belgrano crew don't know half the time!
