The output from my end ileo was always super thick (almost like a regular BM, I told my surgeon it was my first time having a solid BM in years!), the output from my loop was always like running water (lots of loperamide, pretzels, etc until takedown), and my j-pouch is usually somewhere in the middle. It honestly doesn't really matter to me because I empty the same amount (5-6x/day) no matter what the consistency is. The only things that affect my frequency are if I eat *a lot* or if I eat a lot of green leafy vegetables (the only food that really bothers my pouch).
In short -- I think Silent Lucidity is right, it's mostly up to chance.
