I have an 9ft 9wt 3 piece Diamondback with spigot ferrules. Mine broke at the first ferrule (snapped in half) while bringing in a nice brown on te St. Lawrence. I had the rod repaired and sent back to me in about a week. No small task on shippings between Canada and the U.S. I also cannot complain because I won the rod at the first Salar@ Margaree Clave. All this happened under the previous ownership of Diamondback (Barton Merle Smith was the owner then). I know that since then Diamondback has been making sleeve over ferrules. I still like spigot ferrules though.
