I think I agree with this until you are really confident, no point in losing noted prayer pots and food if you make a mistake on your first tries. Shades of Morten quest allows you to use the general store in Morten to unnote supplies if you want, in addition to In Search of the Myreque for the shortcut from Canifis to Barrows. A real time saver is having a Canifis portal and altar in your house. Tele there, recharge prayer and use your portal back to Canifis to bank. House teletabs save inventory spaces. Good luck with your Barrows runs, it's addictive :D
