have a set of 8ca weights empty right now and I was thinking about trying them in my piped cpr viper. changed the top gear down to 21 any suggestions where to start with how much to add to the weights, primary spring, and what helix.
8ca 4.5 heel, 2.4 tip, green/white/green primary spring, 15mm rollers, 50/40 helix with green at 70-80 twist.
