Trout: Setting the hook

[Mark Steudel]

So I was with one guide, and he told me that when I set the hook, it
needs to be like a back cast, I was just getting into fly fishing so I
did as I was told. But as I fished more, I've found that I don't need to
haul in on the fly so hard. I can usually just gently and quickly lift
up my rod tip to get tension and that's usually good enough. How do
others set the hook when fishing for trout?
