I'd recommend just using the old camp trails external frame for a few trips, just to get your feet wet again. Then, if you're excited about putting together a newer, better kit, look at upgrading some of your other gear before taking the plunge on a new pack. You're much less likely to waste your money if you wait a bit before spending it on a totally unknown quantity like the pack you linked to. Sure, the photo looks good, but you won't be lugging the photo on your back.

Happy hiking!
