I think all your thoughts sound quite reasonable atm. As a fellow ltttc'er I get the age thing, the planning thing & the wanting 6 children thing! I can imagine its frustrating that you know you will never have a surprise. It makes the decision to stop seem so final. Perhaps after your second child is here, your feelings might change again. And if you are lucky a third time, you feelings might change again. Or your last embryo could split in to two, you could have twins... then you would have 4 children?! Who knows. I guess you wont know until it all happens, but that might be something to wait for.

Personally, I always wanted a big family. Like you, I wanted at least 4, up to 6. But after having my precious boy, I look at his sweet face & know I would find peace if I never had another. He is so amazing, gorgeous & I am extremely lucky to have him. Of course I want another, I am aiming to start trying in the next month or two. But I can honestly say I wont be trying as hard as I did to have my first. I just don't have that sort of resolve left. And like myturn, I don't want that sort of ttc strain on my family. Ltttc definitely took its toll. I have one genetically perfect embryo, and a couple of day 2's left. I doubt whether I will do another stim cycle after they are gone. Who knows how I'll feel when that time comes, but its how I feel atm.
