I have a custom SU1508 breakaway built by Nick Myer. Awesome rod. These rods are what are known as hattaras heavers. Specific applications are weight and bait or tournament casting. They really get some great distance if thats what you are looking for.
The LDX is rated for tossing 3 to 5 ounces and the newer HDX is rated at 4 to 8 ounces. They are the mass produced factory models breakaway introduced a few years back.
I think they are fairly light for the size at around 13 ounces if I can remember correctly.
Anyway have a look at their web site at breakaway usa.
