I wasn't too sure what your original question was, sorry. Biggus may well have answered your query - if I can help you at all, and not wanting to engage in guerilla marketing, pm me or e-mail me at work - you'll see my contact details on the bottom half of page 29 of the latest issue of Pennant (which may have thumped onto your doormat today!).
