HEDP,
You know you are fishing - certainly from our own experience at Wattashame as they are all pulsing down through the line with bits missing and then having to re-enter back at the original points to have the bits missing fitted
Ah, but to get to the bits that need fitting they then have to remove the bits done further down the line in order to retrofit the original bits missed.
Confused and surprised - go and have a look for yourself - lovely shiney hangar though!
But from the sounds of it Odiham are having as much success or answer B....
