Hi PE,

Thanks for replying and sharing that.

Its interesting that Lambrecht and the Kodak guide you refer to advocate the same orientation, while Jilg & McNutt advocate the alternative - and Howard Bond has PROVEN (to my eyes) that the alternative works beautifuly. I conclude that perhaps it doesn't matter, but will have to try both and see for myself.

Thanks again
