The person who sold me the second kit sent me a couple of those tips you guys were talking about. They are plastic, I'm guessing these are the whistle tips?
I tried one, and it does improve the hit. I had found that not putting the rubber stopper on at all really improves the hit while I'm at home, but I don't want to carry it open. I think the rubber stopper end gets loose after a while. The plastic tip has a very tight fit, which may be why it hits so much better.
