US Entity structure for Canadians

[Hai Loc]

I would like to hear thoughts from Canadians how they set up their entities in the US and why they decided on certain structures based on investment/exit strategies. 

I have seen LLLPs used, LP used, LLC owned by C-Corp owned by Canadian Corp and I have seen personal name with added insurance.

I am planning to restructure all my entities and my decision will be based on research that I will be conducting on my own plus some help from high end professionals.  

I prefer not to hear "seek professional advice" on this thread. Just thoughts... I have taken professional advice on this spectrum in the past and for the most part it was not the best.
