Hi. I too am a Theorema enthusiast. I have not tried the Leggero but I have tried the Esprit d'ete which, for a flanker, is marvelous. As you know all three types are discontinued so, I have been snagging them up where ever I see them. The Esprit d'ete really reminds me of summer and the beach so for spring and summer I use the Esprit d'ete and fall winter marks the use of Theorema. Good luck.
