I've always been Drennan and Kamasan, However I've not used a single B911 this year which was before, My most used hook. Admittedly I've been using some Drennans still for silverfishing but not as often as I did before. My 3 hook cases, which consist of maybe 6 hook lengths in total are all Guru. I know that doesn't say much.. At all. But still.
I wouldn't use Guru on Rivers though. Most people I know do pond / commie fishing. They're all loving Guru hooks. I even see people raving about them on fishing pages I follow on Facebook.
By 'Killing the hook game' I don't mean dominating the market. I mean they make some pretty damn good hooks. IMO, some of the best on the market.
