If you want to really please him give him a gift cert to a fly fishing shop. Put a Picture of a rod in his card along with it.
Or better yet get him a ORVIS catolog ( they are free ) and wrap that up with the gift card
I am sure he will love this and will negate him returning a rod he wont fish or already has. We flyfishers are pretty selective about our tackle. What one person might love might not fit the hand of another..
Hope this helps
