2x50m is definitely enough for The Clean Sweep anchor. Traversing along the top of Taipan from 7th Pillar to Clean Sweep gives me the heeby jeebies so take care. In particular the red line in this picture is grade 8-ish soloing on dodgy grey stapytlon bollards on the lip of a 50m fall - the green line is better but you could still seriously stuff up (especially the bit above Father O) so take care.

actually a single strand 60m will reach the ground on stretch from anywhere on top of Taipan...but there are no anchors to rap off, so the Clean Sweep anchors are your main option. (I think the (new) Father O anchor is just below the lip so would be pretty scary to access from above). There is also new DRB at the end of the 3rd pitch of Seventh Pillar and 2x50m ropes will get you off from there though you'd miss out on the nice last pitch.
as for thermal cycling, I have also seen this in horizontal breaks on Taipan - a #0.5Fr resisted an hour of cleaning efforts in hot sun, but later came out easily in 2s in cool shade.
