Nice fish! I can see how a particular wood grip might fail with one of those, or how a light and strongly bent blank might fail near the grip with one of those fish attached. So far, though I've caught sizable fish on my lightest rod with a wood grip, I haven't had a blank fail.
I chose the maple because it tends to be a pretty strong wood if it's not burled, and because the curly maple I used seemed to echo the cork rings used in a conventional grip. Couldn't figure out how to get an image into a post, but I did get one into the gallery where I could retrieve it with a search on my username. This rod was made up about 5(?) years ago. It has not been mistreated, but hasn't received any special care or maintenance either.
