These heavier Stonze™ were created for the circumstances when that extra weight is needed, e.g. boating out your baits or fast flowing waters.  Boulderz still benefit from the overall concept of the Stonze™ System, just bigger to the naked eye. However, to the fish they are merely another stone on the lake or river bed - a 1oz lead weight appears bigger than a 5oz Boulderz, because stone is naturally occurring, whereas lead is not.

• PS37 Boulderz - approximately 3.5 - 5.5oz
• PS54 Silt Boulderz - approximately 3.5 - 5.5oz
