Even if the knock off lures work just as good as Yamamoto's, there's still all the reason in the world to stay with the Yamamoto lures. The main thing is that it's a great company with great customer service, everything is top of the line, the magazine is great, the man himself is as nice a human can be, they offer so much knowledge not just lures, and they have make you feel like its all one big family. I have been infinitely impressed with this company and I reward them with my purchases.
I ordered some lures online and I didn't get a confirmation email and so I emailed them, well before I could even get a chance to check my email they called me and told me about a small problem that they were having and then sent a thank you note with my lures in the mail. good stuff. I have like 4 or 5 more stories just like this about GYCB and thats why I continue to fish with them even though I do use the knock off lures as well. In fact it has been a while since I made a GYCB purchase (I only buy them over the internet), I have been buying the tiki sticks lately.
I had to edit this post to say that if I fished ALL THE TIME and I was using bags and bags of soft plastics, I would switch to cheaper versions in a heartbeat. But thats not what i do, so i fish yamamoto style biatch.
