My vote goes to 'TKL' ( Zero gravity series ) - as my 335 - alike sits in one. Shaped to the guitar and very light, but with great protection within. :)
* EDIT*
I forgot to mention, that despite the conventional 'Gig Bag' appearance, the two larger outer surfaces of the case, seem to have a solid ( plywood ? ) insert, that not only help shape the bag to the guitar more precisely, but also provide a good former for the inner cut dense foam ; thereby making the whole thing very close fitting - and kick / knock proof.
Looking at the current version of my case on Google, I notice that the ( now bigger ) outer cable pocket that they have since added to the design, seems to hide the otherwise well defined shape beneath - as I have on an older style one. *
