I think I read that you only use bait or mostly bait. You aren't talking lures with that are you?
Check out these fiberglass surf blanks
Some are rated up to 20oz! I have the 11'6" and that thing will heave an engine block!
I couldn't find a whole rod all built, but you can easily make one. I think a fiberglas surf rod is probably the easiest thing to make. Forget about looks for now. Find the spine, put on the tip and reel seat (or plate type!), test where you want the stripper guide, then put the other guides on to take up stress on the blank. when you finish that, put cork grip tape on, and then electrical tape the ends so it doesn't unravel. Done! Parts may cost a total of $200 or so.
