Hi Hooked,
13oz :shock: Never Dude, Biggest we would throw would be 7oz maybe 8oz. As we are fishing for smaller fish, the bigger rods over here tend to have very soft tips to detect bites from small fish and also to protect the worms that we would be looking to cast. The soft tip really comes into it's own here. If distance is key, and you would like more distance without having to learn complicated casting techniques then the longer rods will help for sure.
