Well your portfolio may have lot of protected assets already IE: 401ks, IRAs, In Florida Annuities, in some state Homestead (primary house IF registered as Homestead).
It would have to be irrevocable to be fully protected. My biggest worry with that is that if such trust wraps bunch of equity ETFs and lets say distributes all dividends to you as beneficiary (I Think) it would taxed at higher rate then qualified dividends.
Big benefit is if you have more then 5.34 million
because you can use trust as vehicle to pass money to your kids without estate tax.
Those are kind of the things that pop to my mind....
