stay with a backpack i used a fanny pack for about a day lol i carry pop and stuff with me and my pack probably weight about 5-8 lbs the problem i had was the pack would sag down and it would push against my pants making them want to fall down so i ditched the pack and went back to the backpack. one thing i have learned from a backpack though is when you find one, make sure it has a strap on the shoulder straps that you can connect across your chest, it wont let the pack fall off of your shoulders, but thats just my opinion
