my advice is pick flax in seers and bank until you have all teh flax you need. then once you have all your flax go spin it upstairs of the house north of the yew trees.
i really like barrows and have made alot of cash off it. but i guess if you are sick of it you could runecraft nature runes through the abyss or you could try staking. staking can be a great way of making money.
