How thick is too thick for a B6 notebook?

[notedamy]

I've been comparing notebook sizes for something to carry around, and B6 keeps catching my eye. I'm torn between having more pages in one book and ending up with a bulky spine. For those who use B6 notebooks, around what page count does a notebook start to feel awkward to carry?

For regular carry, a B6 starts to feel bulky to me at around 250–300 pages. Thick paper or a rigid cover can make it feel bulky sooner. Check whether the count refers to printed pages or physical sheets, since those aren't the same.
