My fiancé and I want to get in to 3 gun and we are looking at shell holders. We will be using the same gear for the first year. I want to load 4 and her hands are not big enough to load 4. She can load 2, just testing different loading techniques, and like this method a lot. Which one will will give us the most flexibility? I see a lot of great things about carbon arms. I'm just wondering if someone is in the same boat and has two different people loading from the same gear. Any thought or comments are greatly appreciated.
