Partials Hypothecation Method - Have you used it and why?

[Brett Burky]

We're working on something and have come to love the idea of the Hypothecation method for closing partial notes. We're trying to get an expert opinion on it to be more well rounded on the subject as we dive deeper into that. 

Has anyone ever run into any snags, what would be worse case scenarios with it, do you like that over other closing methods? 

Really just trying to do a deep dive on the subject matter. Thanks in advance.
