The Go-To Manufacturer
Hi-Tech is my Go-To manufacturer for topper laps. These last the longest and always outperform the cheaper laps. What I really appreciate is that as they wear, they are still useful as finer grit. I have some 600 grit discs that I still use as something closer to 3000 grit. They are awesome.
