If you could only use one spotter.....

I'm a firearm geek, I own firearms that are big, small, long, short, bolt-action to FA, single shots and drum fed beasts, I enjoy them all. But if push came to shove and I had to pick just one it would likely be a .22 rifle as I can accomplish almost anything with it than I could with all the rest, it may take extra work/planning on my part but I can make it work most of the time.

I know the best way to clean carpets properly is to have an arsenal at the ready, a little of this, some of that,...
