I have both the regular shape cut, and the plus(same, just a little longer 12 vs 18 inch-slots are 1/2 inch increments) I also put dots on the 4 corners to keep it from slipping). Its on sale right now, you might want to try it out before investing so much money in a system unless you have your heart set on it. I have never tried the pro one I think it only has slots every 2 1/2 inches
