Thanks, Titus. It was all I had that was the right size, so it had to do. Fortunately, the edges of the break married up perfectly, so it was a fairly simple job in the end.
I'd already "replaced" it with a Browning Commercial King F1 ten footer, but it's not as well balanced as the Pro Performance rod. Part of that may be down to the ultra-short handle on the Browning, which means that the effective length of the rod in front of the handle is increased by 6".
