For anyone who's interested, I wrote a bit about my exploration into the issue here. And I'm more than happy to share our proposed plan, if anyone else wants to take a look.
Just want to say kudos for figuring out a plan that you're comfortable with! Honestly, I have no idea where I fall in this whole thing - I may be 100% comfortable with the recommended schedule or maybe I won't be and its something we'll visit as we get closer... but I think its great you took the time to do the research yourself and are equipped with all of the information now. GL in these last few days!
