  We search for effective axions with super-Planckian decay constants in type
IIB string models. We argue that such axions can be realised as long winding
trajectories in complex-structure moduli space by an appropriate flux choice.
Our main findings are: The simplest models with aligned winding in a 2-axion
field space fail due to a general no-go theorem. However, equally simple models
with misaligned winding, where the effective axion is not close to any of the
fundamental axions, appear to work to the best of our present understanding.
These models have large decay constants but no large monotonic regions in the
potential, making them unsuitable for large-field inflation. We also show that
our no-go theorem can be avoided by aligning three or more axions. We argue
that, contrary to misaligned models, such models can have both large decay
constants and large monotonic regions in the potential. Our results may be used
to argue against the refined Swampland Distance Conjecture and strong forms of
the axionic Weak Gravity Conjecture. It becomes apparent, however, that
realising inflation is by far harder than just producing a light field with
large periodicity.
