My understanding is that it's important to keep the shoots in the dark which encourages them to keep tunnelling upwards thus producing long tubers. Only when they got right to the top of the bag did I let them see the light.
I think the danger of leaving them to grow 8" out of the soil is that they'll think they're done growing and instead start to concentrate on flower production. Then you'll have short tubers and less crop. But I'm not entirely sure so I'll let someone else comment :-)
