Faced with similar situation.
In Nov I did CPT-LHR got NF. But would have been happy either way as I had 2K.
Next weeks flight only rows 4&5 are available but UD sought after seats are available. So unsure whether to remain with 4A or move to 64K/62A. Wondering what the general preference is now?
(Haven't flown OF for about 2years now)
