Ok I am wanting to but a silver bullet but I have a few questions before I do. On the site it says to use protected batteries...but eventually I want to get the extension and kick which it says to use imr batteries. So my question comes at this point. should I get protected batteries now and then get imr batteries later when getting the kick and extension? or would it be ok to get imr now and just get the extension and kick later? I had went back and forth on buying the silver bullet and the bolt...but in the end I decided I would much rather pay more for the american made one...Besides that the button you guys use looks so much better to me.
