Troy Petteway has flown with BOTH airfoils on his KR. He did make some other changes also when switching to the new airfoil but I think the bottom line for Troy is that he likes the new airfoil. That may be as close as we come to comparison data for a time unless someone has some documented data and then switches wings. Larry Flesner
