Cuts well, but is not my thing

I ordered the circular blades for cutting materials. That it does so, no question (for continuous use, I can not say anything). Mir is the diameter of the blade, however, too large. I did but then found only in use. Since I did not so well with it, especially in corners and curves. Therefore, I have now brought me a roll diameter of 28 mm diameter with Olfa. So I can personally work better. I feel like being able to control the knife better. But this is perhaps a matter of taste.
