I have a suggestion for loading the Rollei. Many years ago, I was the assistant to Al Gescheidt in NYC for one summer. His cameras of choice were the 2.8 Rollei, while he was shooting with one, I would be loading another. He stopped me, and told me that he would now show me the fastest way to load a Rollei, as I was fumbling with the job. He showed me to get down on my knees and place the Rollei between my knees, holding it and then loading it. This gives you a third hand (your knees) to help hold the Rollei. And Loading is simplified.
