I don't think lead is worth it. Like 12 pounds in my case and worth something like 4 pounds of rail meat. Give a six pack to the crew and get more effect.
The foil simulator gives a bit more lift with a 1.5 inch extension, about 3 tenths percent. Not much but it's more than it gives you for shaving the aft sections to class minimum.
Seems the bluntness of my leading edge is a bigger deal. More likely to stall at low speed.
