Hello! I am a TFOL that has been a fan of Lego for as long as I remember. While I do like most building systems (Znap is a travesty) I find that I work best with Constaction, though I do enjoy building with System. My favorite set is between the Taj Mahal and the Ucs Slave 1. If you have any qualms, please let me know and we can sort it out civilly. Have a fantastic day!
