I am debating over the carboy thing - I could go two carboys or one demijohn (14.25 gallon fermenter).
I planned on using washed yeast and making a beefy starter, or two starters if I go with two carboys.
You recc the combined or the two separate approach?
Good point on the evaporation rate - I think it will be much more than before due to the 18 inch diameter versus my previous 14 or so diameter.
You'll get (slighty) "different" fermentations with the two options, but I don't think one is inherently better or worse than the other. If you're trying to precisely match a recipe you've been doing for a long time in 5gal vessels, split them; if this is a new recipe or if you don't care about a perfect match, do whatever strikes you as easier.
