All was good except discussion of filter. I was told that the filter I had was the expensive one and if I wanted to continue using that caliber I had to pay the $100+. The problem is that I had always paid $60 for the previous filters that were supposedly $100+. So I am still confused about the quality of this latest filter. It is obviously not up to par with the previous ones. It only has one large angle so I'm in a quandary about using it this winter.
