I'm one of those guys who loves sight fishing steelhead especially the summer variety. Looks like I need to add New Zealand to the bucket list...

Steelhead are odd. I've had times where I'm keyed in on one and just as I'm getting in its zone another one will fly in from 50 ft. away and chomp down. I've also had my gear go by and once it was 30 ft. below the fish decided to turn around and inhale my offering. I guess my one piece of advice would be to approach the fish downriver and watch their movements before making your first cast.
