In my Ender 3 I used a glass construction plate with the typical "yellow" springs. And they seemed too "light" for my use. So I replaced them with these slightly heavier springs. So far I am very satisfied with the results. The bed appears to be more stable and does not drift as much between consecutive probes. Besides the springs I also changed the screws to M4 x 40mm. Standard bolt 35 mm. You can find them here - https://www.amazon.com/gp/product/B07WCTJRHF/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
