Jamie,
Got to agree with Neil on this one. I have a rod, delivered with a broken tip and replaced by supplier, and I got Marc Barnett to take a look at the broken tip and he advised not wasting time and expense on a repair as he couldn’t guarantee it with the tip being so fine. He put a tip ring on the slightly shortened section and all’s well. My mate used the rod on the Wye a couple of weeks back and I was able to observe the action when he played fish and I can only say all looked well. The rod, like yours, was broken approx 1.5 inches from tip end.
regards
Bill
