This has been a great read Nino - job well done.
Any chance of doing CV next?..

ps - not a fan of the leds though. I've only experienced playing just the one pinnie decked out with leds (CFTBL @ The Northcote Club).
I can vouch that playing the pinnie in a dark place like this, they do work great in providing so much light. But for home use, a room light switched on and an unchanged pinnie works for me.
