an out turned eye is best when using stiff rigs, keeps the gap open better. size wise, i d go to a 4, so you got a could chance of getting it away or out of weed bed,6 would be as low as id go.
im using fox arma at the mo ,i think theyre called the SR their out turned version,though most companies do them,some called them chod hooks, but as long as it turns out its fine,you can tweak the shank of hook to get the effect if stuck, but id wouldnt want to risk it.
