JT,
BFL is easy because dumb pilots can see on a Jeppeson chart how long the black bit of the runway is - all that RESA/Stopway/clearway is confusing. From the manufacturers' perspective, data presentation is simplified dramatically and therefore it is soooo much cheaper!
We always work unbalanced because reality rarely is balanced. We actually throw away most of our payload in our take-off splay conservatism (based on realistic radii of turn, based in turn on practical buffers on placarded operating speeds), hence we maximise the runway weights (although we have long applied practical line-up allowances!!)
However, I must say that I was drawn to a little curiousity about your attitude to maximising payload through use of the clearway given your passion about runway buffers. Two bob one way??
