As B&S mentioned, going "cheap" on any engine component is false economy. I have Ross forged pistons and metric rings in 4 engines. Have never noticed any noise before warming up. The less friction of the metric rings to me added horsepower over the old school cast iron rings. You can feel the difference just by turning the engine over by hand while assembling it. I also like the added strength of forged pistons. A small butterfly screw came out of a throttle plate on my avatar roadster and it sounded really bad. Only a few thread marks in the head and very little on the piston. I think a cast piston would have failed.
