I never used the toilet rolls, but did the reflector thing a few times. Two kero flares at each end and little cat eye reflectors on stands. With such little light to define the strip on the downwind, it was a challenge in the night circuit as you say. And with a strong crosswind on final your lights didn't reach the reflectors unless you yawed or flew wing down. Much preferred the PC12 for this as the ldg lights are wider spaced and brighter than the nose gear cluster on the B200.
Good times, a while ago now though.
