Thanks for the advice. Here's hoping for the rare chance of the aircraft with the foot cut outs!
99% chance that it will not have a cut out on that route. But I find there's plenty of leg space in the main fleet A321, particularly in the C seat. There's a bit more on the 319s but it must be millimetres, plus the bulkhead has less width. So I'm very happy with row 1 on A321s and I'm over 6ft tall. I guess if you were trying to sleep and really lean back there maybe a bit more space in row 2, but it is a short flight.
