I'm looking at upgrading the Foxpro. At this point, I'm looking at either the Fury2 or the Firestorm. Looking for input on which one would work best up here. Is the Fury worth the extra $100, seems like it would be since it comes with 50 more sounds and a few more features. A few questions I have are; volume, sound quality, remote and call function in the cold. I'm open to other suggestions as well.
