Is getting a small radius of 3.5 or 4 feet even worth it? I have some serious back and neck troubles and I doubt I could handle throwing anything much larger or heavier. I'm not even sure I could even throw a smaller one for that matter, but I have been thinking about getting one and giving it a try. It seems like it would be fun (if it didn't hurt too bad) and would be a lot nicer than paying for bait. Do you even get much bait if you throw a small one?

What is the smallest size available that people throw, is there smaller than 3.5? The smaller the better would give me the best chance of being able to use.
