I have a friend at work who has only one arm, he has a good portion of his other arm a little past the elbow, lost in a nasty accident. He loves to fish, he currently fishes fresh and salt water. He was asking me about a fly rod with a longer rear grip so when he had to reel he could hold the rod with his bad arm (his right arm). Where can I find something like this if it exists? I looked at the spey rods but the longest grip I could find was 7 inches. Do they make longer or does it turn into a custom job? thanks for all information ahead of time.
