Contact sheets not useful? You have to be joking. Make the contact prints on the same paper you normally print on. Always at the same enlarger height, f/stop, exposure time, lens, and without contrast filter. It is a wonderful check to make sure we're fully understanding the lighting conditions and subsequent alterations to film processing, making negatives that print with ease when the time comes to make an 11x14.
To me a contact sheet is invaluable. It's the only way I can tell with certainty, without a densitometer, how I am doing with exposure and processing and whether I need to make adjustments or not. Making negatives that print easily guarantees less waste of paper. With Ilford Warmtone being $135 for a 50-sheet box of 11x14 today, that's worth a lot to me.
