Use what ever size you are comfortable with. I have very small ones which are only a centimetre in diameter up to the very large ones. It all depends on the size of the template you are trying to cut around, and how many layers of material you want to whack through. I think if you make the pile too thick you are more likely to have distorted shapes. Some rotary cutters are too large to use with some specialty rules and you have to use the smaller one to get around the shape. I have a sewer's pen - knife (like the Swiss army knife - made in the same place, except for sewers) and the rotary cutter on that is very small, very sharp and very handy. My 45mm gets the most use.
