RE: Double vs. triple
Um, um, um,. Well, um, um. I never really thought about that one. I've never really "broke a call in", I just have to get used to them.
Perfect example is the "Lost Poult" that I love now. When my buddy first told me to try it, I hated it. I couldn't make a sound with it. But I heard so many people sound so good with this call I was determined to "learn" the call.
And as of right now, its my favorite call.
As for keeping them. I've had some for three or four years now. I don't use them that regualary though. The ones that I use the most often, I replace every year.
