Thanks for the great replies and photos guys! The consensus seems to be that a little drag will not hurt slow flying 3D planes. Foamies even have drag plates installed on the ailerons sometimes. Yes, sure will fly it both ways whenever I get it going. init4fun, I am hearing that besides knive edge, the SFG's do help with high alpha harriers a lot too. One friend said they hinder the roll rate. Anyway I'm getting used to the idea that they are towed in and guess I'm the only one who noticed that so far......
