I didn't know Rapala made jerkbaits either. First impressions of this one straight out of the box are it's a well-made, good looking lure. It's roughly the same shape and size as a Shad Rap, but without the lip and with finer-guage VMC trebles.
Not every mass-produced lure does what it says on the tin, but they reckon this one will get down to 5ft and zig zag if you bring it in with downward taps of the rod. I'll let you know how I get on with it.
+++They're half price at Harris Sportsmail at the moment - £8.49 instead of £16.99.
