I'm looking for a simple folding wrist-braced slingshot to carry in a hunting pack. Main use will be squirrel deterrent when I'm bow hunting deer. At least a half dozen manufacturers have a model that will fit the bill, Marksman 3040, Trumark FS-1, Saunders, Barnett, Crosman, and I've probably left off a few. Is there really any significant difference in any of these entry-level shooters? The only upgrade I'll probably make is to replace the standard tubes with the red or black. It seems flat bands are on the higher priced models, but I'll probably stick with the simple tubular 'Y' frame, as I may add the tie-wrapped-on, fold-down, whisker biscuit modification for shooting arrows at small game. Thanks in advance for the opinions.
