Taking my friend fishing - Can I put him on the fish? Spring on a Northern river.

My good mate Dave has been troubled by a a frozen shoulder and joint trouble for months, but now is on the mend, so I figured it was about time he started fishing again! but I wondered about how he'd cope casting a fly again.
Turns out I didn't need to worry, his fish catching muscles are in fine form!
Nymph, Dry fly and Streamers all had their turn as we entered the finest fly fishing month!
my tackle - 10ft 4# dry fly / nymph outfit with a DT floating line
9ft 6# streamer outfit with a intermediate FT line
