And I'm hoping I've also given myself enough time--like, a reasonable enough timeframe--that maybe I might be able to go over it and probably finish faster too.

Haha, I don't know what mine is. Scene by scene, I guess, but I don't really get into a groove until later on, I don't know. The beginning seems to always be the hardest. Different strokes!

And yayyyyyy! :) I like your idea of two betas--one that's there from the beginning, and another that looks at the completed version fresh. I think having someone working with you from the start is going to be really helpful with a long fic, but both of you will naturally have a bias that a totally new person won't have. I might not get started on this until June, but if anything changes with your schedule just let me know; otherwise, I'm stoked! :D
