Sigh.. modern stuff.. always making things complicated.. bad enough those American verses British panels - i don't know why they never made those bridgie handling parts more egonometric - you know a bend in the carrying handles to ensure equal distribution of weight -thinking MGB here... I was put on a back course when in NDHQ (after going topo-surveyor) and they told me -"If it is not safe you have a right to refuse.." That sort of indicated to me that there was a bit of a disconnect between "Puzzle-Palace'' and reality.. Certainly though some equipment could be just slightly redesigned.. and save alot of people life-long grief - Hey any-one notice what comes up when the spell-check does ''puzzle-palace''? Neat!
