so Im making a custom handle mold, for my rackets. Now I dont use a grip, usually just an over grip or two. which typically means I have to add lead to the pallet to make up for the weight lost from removing the grip. So I was contemplating what it might be like to use a polyurethane, to form the grip rather than a the typical dense foam. Additionally they polyurethane would have a bit more weight to it helping to make up for the lost weight of the grip. And it would have a bit of give to it as opposed to the hard foam. any thoughts?
