I was in the shop the other the day, they have a 12" on the shop floor. One thing that you notice straigh away is how small they look compared the Light Bridge, I think they have a much smaller f ratio. Also the lid for the primary is a much better design that the Light Bridge as it fits onto the bottom section of the ota and not directly onto the mirror itself. I'm always fearful of scratching the mirror when I put the cover back on.
