I repeat (If it's OK for Harribobs, it's OK for me), after the initial gridfill, this puzzle was a mind-numbing bore, a festival of drudgery, a joyless tide of ennui, a Sisyphean heap of tedium, a dreary, wearisome, pile of repetitive donkey-work and a balls-aching grind. Apart from that, it was alright. If you are in the process of concocting another of these, Harribobs, please stop right now.
