we are looking for a little more density but still achieve a moderate flotation,with hardware on the bait. with my new mold design the tail half is less in diameter. that's why we have asked. along with density,,strength and wired thru. although its only a 7 inch lure for predators we need maximum strength.thats what led me to 26lb foam instead of 16lb densitys.. on our 10 inch bait 16lb has done very well in test,,catching and durability.
