That's a great point. All we've ever gotten, with the exception of MUZM set, were Heaters.I finally got tracking information this morning, looking forward to this pair. I wish Oakley would do a proper limited release of these like they did with the SubZero's last year. A set of Heater and a set of sweep lens variations, or offer both lens size in each pair like this did with this set. But with black and violet or black and sapphire lens colors.
