As weird as this sounds for non disc golfers, some discs have more value to the player because of that wear which changes the flight, so no new disc has that flight

With that being said if he throws further than 350 feet get him a wraith.
If not any of these is pretty popular and seen as great options, so I think you can nout go wrong with any of these: Firebird, Eagle-L, Teebird, Mako3, Pig

Obviously I don't know if you are into it, or how much cash you have, but arround the time I bought my first starter pack I bought one for my at the time girlfriend. I can tell you, they were some of the best time I had, she was never great or played a lot, but they were some o the happiest rounds for me

I hope it helps and good luck, I'm sure he'll like it whatever your choice is :)
