I've got a Shakespeare K2 Team Extreme LDC 18ft Rod, which was a surprise birthday present off the wife a few years ago. I didn't think I'd have much use for it at first as it seemed very flimsy for our coastline, but it gets out when I'm fishing clean beaches and it's an absolute dream to cast and fish with.
I use a 4oz gripper (max) with a clipped down rig and I've never had a problem with bait not staying on the hook. I also find it a breeze to cast and the distance you get from a simple overhead thump is unreal, plus the bite detection is second to none.
However, I wouldn't dream of using it over rough or snaggy ground, if there was any sea on or with the suggested 4-8oz weight range, as I think the tip would part company with the rest of the rod, as several long rods already have when cast with 6-8oz of lead.
