I think that the Stealth mode vs not Stealth mode argument is just complete nonsense. If Flarm (not in Stealth mode) does provide a tactical advantage, then all pilots with Flarm equipped gliders have the same advantage. Therefore, no Flarm equipped pilot has any advantage over another Flarm equipped pilot. Assuming Flarm does provide a tactical advantage, the only people who lose are those who do not use Flarm.
