Don, In my experience with technos, the biggest factors are: - people can't see as well, and dances are often more crowded, so stuff with higher collision potential are out. Orbits, pousettes, star promenadrs ... Caution! - you draw a slightly different demographic, often newer dancers, so the overall difficulty is lower and you're calling longer - people get lost easier with less lighting, louder music, music whose phrasing may not be as clear, and the trancey nature of it. Again, calling longer. - Matching balances can be a lot easier or harder, greatly varying on the songs. Good luck and have fun!
