ROC while living in another country for +1 year.

It's been a while since I've posted anything on VJ, but I hope you guys can answer some of my questions (I LOVE VJ!).

My wife and I have decided to move to Quebec Canada (my home country) so she can perfect her french (she plans on going on for her PhD in French Lit). To move to Canada, we're going to play role reversal in the sense that I'll be sponsoring her immigration to Canada to become a Canadian PR. I'm very supportive of this, however, I'm very confused in terms of what we do about my cond. perm. residency here in the US as it expires Feb. 2011. We're looking for the easist route possible to re-enter the US in late summer 2011. After researching a bit on VJ and on google, here are some situations I can think of:

1- Just move to Canada after Canadian PR card is received from while living in the US, allow my US Cond PR card expire and go through a CR-1 immigration process or a DCF process, if possible, in March/April 2011 (to have time for it to complete come Fall 2011).

My question is, will the allowing of my PR card to expire affect any future immigration applications? Especially since I plan to re-apply shortly after the first one expires..? Is there a way I can cancel my Cond. Perm residency before we leave so when we apply again in the future, it won't be as confusing?

2 - second option: apply for a 1-131 travel document before we leave to try and secure re-entry into the US when we're done abroad. However, I've read the I-131 will expire when my 2 year cond. PR card expires (Feb. 2011). So, this leads to option 3:

3 - Apply for I-131, try and maintain residency in the US while abroad (investments, banking, mailing address, driver's licenses, anything else that may provide evidence for US domicle while abroad), apply for Removal of conditions before my cond. PR card expires (apply for this in the US but list our Canadian address as place of residence and list out US address as mailing address), live in Canada on the I-751c extention, if given, and then move back in fall 2011. This is confusing. I read another post that discussed a similar situation (here)

But as I said before, we're looking for the easiest route! It would be nice to keep residency, but I'm afraid it might be difficult to prove we're still residents of the US since my wife will be getting her permanent residency for Canada...

Any advice will be greatly appreciated!!!!!!!!!!
