I have taken smart nutrients before and found good benefits from them; Ginko, Choline, Piracetam, Hydergine, etc. I was wondering if anybody knows what combos and what ratios work the best, especially for memory?

To the best of anyone’s knowledge, all combinations of those unregulated drugs are equally effective at improving memory. The combination which is best for maintaining the thickness of your wallet is a mixture of 0% of each of them.
