Barrows is the wy to go with your stats, there not really any other ways. The thing with barrows is you train mage, attack, strength, defence and hitpoints while making money. Do 100 trips of barrows and you'll have a decent 20M+ in your bank, which you can use to buy equipment to train until 80, 80, 80 combact and then have enough to solo/duo Dk's which are twice as good as the barrows brothers.
