The truth is the rod will cast 4 to 6 OZ jigs great. I think Breakaway rates it to 8 cause they consider it a "mini heaver". They say its good for tossing 8 OZ sinker plus a small piece of bait like a clam or sand worm or squid chunk.
I think it can toss the 8OZ and it can certainly handle 6 OZ jigs perfectly.
Some ratings are funny. the blank that the 1265 is made from is rated 1/2 to 1 1/2 but it won't toss 1/2 well and it will toss to 3 OZ well. Go figure???
