Good on hard bottoms, the short condensed shape of this lead coupled with the two flat sides makes it the perfect lead for bolt rigs at short to medium range.
By its very nature the flat pear lead lends itself to being fished on marginal slopes, the sides or back or gravel bars and in rivers and is most effective at short to medium range, it holds so well on the lake bed and offers good resistance to a moving carp.
Another feature of this lead is that it looks like a stone on the lake bed and during the Filming of Parts 1, 3 and 4 this lead blended in better than any other.
As with any lead finds it the easiest path through the water to the lake bed, so a nose heavy flat lead like this will plummet down side on and nose first, this will less effective in the silt than say a Swivel Pear lead.
