Oooh, try Green/Red Oriental Spinner lure with Heroic/Lunker combo. It only attracts brown trout, salmon and the Bothriolepis.

Just remember to TWITCH the wiimote back and forth to make the lure move and attract fish with it.
Okay... you should feel 2 type of vibrations with the lure. One is a soft vibration, it could only meant that you're rubbing on something (weed or fish) close by when you're moving the lure. Don't ignore this, use this to your advantage, you may be rubbing a fish. So keep twitching in that spot than further away from it. You know you got a bite when you got a much bigger dull vibration, pull your rod up to catch it successfully. And don't twitch ALL the time, just let one twitch to let the lure settle. Once it settled, give it a few seconds and then twitch again. I find it hard to "capture" the fish when I'm twitching the lure because jerking the rod would also define as twitching and the game would confuse the two. :\ So yeah, be consistent with your twitching and your jerking the rod to catch the fish.
As I said in my guide, I catch this guy 90ft out in the grassy marshes downstream. I wasn't expecting my FOURTH catch to be the S rank. I was so dreading these lol kind of catches. But man doesn't it feel awesome to get them then.
