A new tip is inexpensive and worth trying. If you don't like the way it casts you'll only be out a couple of dollars. If it works you will have salvaged the rod. tips are measured in 64ths of an inch. To find what size you need take a calipers or micrometer and measure the rod blank diameter at the point where the end of the tip will come. If you don't have those tools take your rod to any tool shop and tell them what you need. I'd be surprised if they charge you anything just to measure the tip. One sixty-fourth is roughly 15 thousandths.
