If you are using canned cream and a disposable, I would suggest you find out more about DE shaving. The prep is largely the same as for a straight shave and you'll learn about multiple passes and changes in technique for WTG, XTG or AGT. It is important to learn how to make a good lather that is slick and has some cushioning. I wouldn't use a straight with anything that comes out of a can. Just my opinion. As always, YMMV.
