just a thought. have you ever had a loose batten in a strong blow. both times it happened to me, i finished the day with a trip to the sailmaker to repair the hole where the batten pocket wore through. i really think the lower hook will do the same thing. if you install the hook off center, you might have problems making the ring catch the hook. if you do install the second hook, let us know how well it works. i suspect if it doesn't work well you will know after (or maybe during )the first day of use.
