Indeed it seems that also in "laatikko" class the single-k is more popular. Here are numbers from Google searches: laatikoiden 114 000, laatikkojen 9 800, laatikoitten 3 600; laatikoita 242 000, laatikkoja 10 000; laatikoihin 78 000, laatikkoihin 6 600; laatikoina 10 000, laatikkoina 3 400; laatikoineen, laatikkoineen. If one chooses another word, one gets different result. With "valikko" the frequencies are more even (ratio is btw. 1 and 2), and in comitative the double-k form is more frequent.
