Not talking about pine pellets....

when using kiln dried pine shavings for your rats, do you prefer it to be
1.) cut into little thin tiny pieces
2.) longer, very thin, curly shavings
3.) thinker fatter straight shavings

AND WHY!!!???

My local feed store has all three to choose from... all priced about the same. The one cut into little tiny pieces gets you the most for the buck (in weight) but because it is such small pieces, you have to use more of it then the bigger cut stuff....
