"First rod" Old Dad speaking here ...
If the munchkin has shown a real interest in fishing, let them pick out the first rod (that's appropriate for the fish your going after) and reel. You don't have to stand them in front of the Sage display.
Did this with one of my kids (Big PS here: I went to the shop and clued in the owner what was going on so he was totally in tune) and it was one of the grandest experiences of my life. Shop guy was just great; he knew he could sell anything he wanted, but didn't even get close to that.
Dad stepped back, let the lad do his thing and he still has that rod and uses it. Memories are priceless.
