A couple more Viva variants worthy of your attention. Rather than tie them on size 8 or 10 hooks and fish them as out-and-out lures, I like to keep these two Viva variants on the small side - 12 or even 14 - and mix them up with wets and/or cormorants etc.  It goes without saying that they're a first choice for early season work, but don't forget them through the summer either if the water gets murky.
