Peter, I'd go for the large pots. Not sure that grow bags on end will have sufficient girth.

I have used those potato grow bags. The are cylindrical, about 20" diameter, and they have insufficient girth. They stunt the growth of tubers, as at the level they are produced, the plant tries to spread out its roots, which the bag checks. I get fewer and smaller spuds than from just slightly larger enclosure for the compost that I construct from bricks.
