Understood re: the barrel connector now! And yes, I wouldn't wish to doubt members opinions here either, but I can see that your A/B test is certainly preferable to comparing to memory.

Many thanks also for your generous evaluation offer - I used to live in Ascot, but now live in West London - so whilst Pangbourne isn't a million miles away I certainly wouldn't want to put you out! But thanks very much anyway...!
