Lead Shot is best an is pretty expensive an is the best to do but in case u don't wanna drop the Dough u can get Sand an jus keep packin it in there will suffice , but i would go with the Shot if u got the $$$$ lol lol oh yeh an make sure u put something around ur Balls it gonna b HEAVY lmao when u lift it an move it

If You Are Gonna Do It , Do It Right !!!
