Yah... they just larks head onto the br3 lines - so it's a daisy-chain of larks head all the way down from the top... looking at that diagram, maybe
it won't be as bad as I imagined - I'll only have to undo the Z lines, nothing else.
But if there's a sneaky way to un-larks head a connection... that'd be good to know
cos SZ1 joins both BR1 and BR2 which makes it tricky...
Yeah... I got a kite. Or two...
