I have a feeling we’re going to continue to see the prices of the S & T series fans increase across the board to make room for the A & B series fans.
Aside from them appearing to be all plastic, I can’t see any other significant difference between the Cloudline LITE (A & B) and the Cloudline (S & T).
That said, I might consider an S6 plus a Controller 67 for $160 vs a T6 with the older model controller for $150.
