PHYS/PSLV as Substitute for Gold IRA

Hi Everyone;

This is my first post here. TF, this website is a really great source of information for all PM related topics.

Here's my question: Would PHYS/PSLV act as a good substitute for a gold/silver IRA. Rather than close my current 401k/IRAs and transfer them to one of the many gold backed retirement plans, would PHYS/PSLV work just as well as they are backed by actual physical gold and silver?

What are everyone's thoughts?

Thanks.

Bill
