Siwash is the hook you'll want if you're going single. Make sure you take and bend an offset in the hook point from the shank. Example being, take a lay a siwash hook on your coffee table, next to it - lay an octopus style hook. Notice how the octopus hook does not run parallel with the shank of the hook, and the point turns up at a slight angle away from the table, and the siwash lays completely flat.
Take a pair of pliars and bend your siwash to match the octopus.
This is all my opinion, but it will help with the hook up ratios. A flat siwash has a better chance to pull right back out of the fishes mouth.
