Bought a number of Mog books recently, including this one, but am reading them in a different order.

I've left this book in the UK, so will have to wait until in am back on the 23rd - briefly (!) to pick it up.
Did I read that you are thinking of maybe swapping your Plus 4 for a Plus 8 - you really can't beat the sound of that V8 and the wall of torque is brill too.
