I just received my Dyno-Thane The Thing Returns. When I ordered it I went with my drillers recomendation of 3.0 oz top and 3.5 to 4.0 pin. Chris from Buddies called to let me know they did not have the TW I wanted. He told me what they had so I called my driller. He said what they had was good. Called Chris back to let him know. They shipped Tuesday and got it today. The specs for the ball 15lb 2oz
TW 2.48
Pin 3.5-4
Had excellent communication and goy what I ordered at great price! I definitly will buy from them again.
