If his rod has a screw in stopper just make a extension handle, or see if you can get one made, i have double and single handed rods, i was going to buy a switch rod for spey casting on a small river, they are expensive, i ended up making a extension handle for a 9/10 weight 10ft old hardy single hander, got a 6 weight spey line on and it fly's out, saved me some coin as well. Great for casting under overhanging trees tight on the river edge.
