Best sub to use with BASE?

[terry44]

I have BASE 4G and Overcome Procrastination 4G. Are they safe to run one after the other in a loop, and are they compatible to run that way?

I just searched the store for base 4g and become a successful entrepreneur 4g and nothing came up. I'm guessing it's an old sub then or do you mean base 5g?

Shannon made Base 4g available recently to people who requested it, but said it would only be available for a few months. I bought it in the New Year sale.
