I agree with Lleechef regarding never smashing the burgers. I also wonder about another poster who indicated covering the burgers and letting them stem for a while.
The Sundancers main problem has been with the burgers getting hard on the grill. I guess they taste OK but they are crispy and hard. I tried cooking them medium or rare but the family does not like that. I just wanted to get a juicy burger.
