I got 6C all the way.
Just nice as long as you keep moving, hand were getting cold towards the end of the 2nd dive though! 54 mins.
1st dive we did the cockpit, coach, Staingarth, APC, Nautilus. The vis wasn't that good to be honest. 2nd dive as Leigh said Wooden Boat and Cessna, much better vis over there. The fish on the way back make it for me, the shoal of roach, pike and the massive perch.
And not forgetting the odd air ring or 2 blown along the way
