Just reviewing because I received the product today ^-^
I bought the 60g long springs and compared them to a regular length 67g spring. The long spring did well in terms of being snappy and having a good initial force to it :). If you want to get into spring swapping these are some really nice ones to go with. I haven't tested much or record the sound to see whether any ping could be detected but for now, definitely 5 stars, ty knc :P (they came with gummy bears)
