The 4" drop belly does everything, whether you want a steady side to side action or give the impression of a frantic fleeing bait-fish, it will do it all. Small enough for perch to hit it, but man enough for the most savage of pike takes.  
At 60 grams this can be worked at a lighter end of the jerk bait scale and yet puts a great account of itself with standard tackle.

The last batch of foils, although everyone was happy with them, had a slightly slower action due to the added foil and added 'tex. This batch, the bodies have been made 1/16" thinner. That means the foils are now the same size resulting in the faster action.
