I cooked CKT last night and experimented with using some frozen rice noodles - it turned out very well. There's only 2 of us usually so I had some leftover rice noodles the last time I made Wat Tan Hor - they had been softened in the microwave already and then frozen in individual serving sizes about 2 weeks ago I think. I put them in for 2-3 mins on high in the microwave from frozen and then fried them.
