Well I personally collect flax in Lleyta and bank it until I have a decent ammount. (1k or more) and then to spin the wheel in seers is closer to the bank than the one in gnome stronghold. Most people who use flax as a training method collect the flax/buy the flax first and spin later. That's true I guess, I just figured it be quicker to pick it, take two steps, wheel it, run, bank, repeat.
