Congratulations for digging a little deeper on a topic that seems to get dismissed so quickly!
I bought a whole life policy optimized for banking in 2009 after doing extensive research. I started using it within the first year and don't ever intend to stop. I became an agent in 2013 after being a client first and enjoy helping my clients on a part time basis.
My policy will be "breaking even" on the guaranteed side in 3 more years but due to my using it (taking loans and paying myself back with interest) and the dividends I've already realized I'm ahead of schedule.
The company I bought my policy through and who I now primarily use to write new business through charges a fixed 5% annual interest rate on policy loans and all of that interest goes back into the policy to be loaned out again.
If the policy is optimized for banking you should be seeing immediate cash value from year one and your cash value should equal and then exceed your cumulative premium payments 5-7 years after your policy begins. Make sure that you start out with a manageable payment structure that you can maintain for that first 5-7 years so you don't have to worry about lapsing/surrendering your policy and walking away with less than you paid in. Once you've owned and used your policy for any length of time you will realize that it will never be in your interest to surrender the policy.
If you're interested, I would be happy to give you a second opinion to help you make sure you're getting the best possible option for your situation. Just shoot me an email directly!
