Quite a timely post. A friend of mine who switched from Trager to RecTec about 3 months ago asked me almost exactly the same question tonight. His experience was the same as yours. His Trager fluctuated temps broadly and had a hard time holding them, but overall cooked faster for most...
I rinse mine and then pat them all dry with paper towels before cooking / applying rub to deliver similar results to the fridge method.
With that said, I am always looking for new ideas and am going to give the baking soda idea from @Bytor a whirl as well. That’s a new one for me!
Thanks for posting these pictures. I'm about to buy one of these and wanted to check recommended size. I have the RT-680. Should I get the 4'x6' or 6'x8'?
Thanks.
