I recommend trying Gazzew Springs if the weight you are looking for is not in stock. Gazzew springs are a nice improvement over the stock springs and increase snappiness and the pronouncement of the tactile event https://kirballskeys.com/gazzew-springs/.
If you disassemble your switches please watch this video on the correct assembly procedure to prevent damaging the leaf and causing inconsistent tactility. https://youtu.be/8ZSlVkCLBWY
