Guess I don't know what carbon stocks mean, but if it is still a rod system, it doesn't work very well around here.
The system I am now using is similar to the simple NACRA cleat it down and bungee it up system.., clean, easy, cheap and it works better than anything else.

After Gulfport I gave Seth all the remaining, unbroken rods from the Taipan system and said I will never use them again. If I couldn't find another system, I would sell the boat. That is how much I dislike the stock system.

Good example. I had a great start against 200 boats in the Miami-Key Largo Race and was out with Bill Roberts big boat and honkin' when I noticed I had a lot of kelp on the boards and rudders. So, I cleaned the boards and when I pulled up on the dumb rod to raise the rudder, the entire rudder system jumped off the pintle.
It took me almost a half hour to get them back on.
Never again.

And, of course, in Gulfport one of the rods snapped and I had to borrow one from Seth. Wrong size and I had a lot of helm and the boat was 20% slower.

Rudders can be the Achille's heel of some great designs, i.e., the infamous Mystere rudder system that would allow the rudders to pop up in deep, clear water.., and then when you went over a sand bar or came into the beach, they would stay locked down. Saw some Worrell 1000 Mystere boats rip off their transoms coming into the beach.., hot rudder system alright.
