Quoted from boogies:Has anyone upgraded to a stronger shooter rod spring?
I'd like to 3/4 plunge and have the ball go all the way around.
I don't know if your still looking for answers, but I've upgraded mine to red last week when installing Stern shooter rod. 3/4 goes all the way around.
With the stock one, even a full plunge was not making it 50% of the time. Red is much stronger tho, not just a bit stronger than orange.
