Just wondered if you have any info on the cold water performance of the newer model abyss regulator. I switched to the abyss after my old regulator had multiple free flow issues, and have been very happy with its performance. I have been diving it in 37 degree water (F) with no problems, but the water here can get a few degrees lower. I know that no one can predict precisely when a reg will freeflow, but any practical info would be appreciated.
