I've had fun with swim baits and plastic on the edge and in the kelp. Lots of bass in there.
I don't think there is a more fun way to hook a YT than on an iron but I've made the mistake of using one too close to the edge many times and have lost a lot of irons.
The edge of the kelp is a place that I kinda shy away from because it's so easy to get snagged.
My advice..... Pick what you want to fish for. If it's Bass than hang out in and around the kelp. If you want to go for YT on an iron then move further outside the edge.
Good luck.
