It's all about personal preference here, as far as FWH goes. I like it and feel it improves the flavor of my beer but others have tried it and said they notice no difference. There's a whole lot of stuff that can contribute to "hop presence" in in your beer. Everything from boil times and water chemistry to serving temps and even the glass you serve the beer in. To keep a long story short, try it. If you like it, keep doing it. If you don't notice any difference, don't do it. Simple as that. Now let's get back to brewing, shall we?
