To fish a blue fox vibrax get a proper swing. Start by positioning yourself slightly upstream of where you think the fish are holding. Cast the spinner across and a couple degrees downstream of where you’re standing. Allow it to sink near the bottom and then engage the reel. All you’re trying to do here is to get the blade spinning so that it has enough lift to stay out of the rocks. As the current sweeps the lure downstream, keep just enough tension on the line to keep the blade moving. As the spinner works through the run on an arc-shaped swing, follow your line with the rod tip. At the end of the swing, let the spinner hang straight below you for a few seconds before you reel back in and cast again.
