Jon.

yeah, I suppose it's a choice between 33 and 35mm then.

Check the ERTRO sizing on those Vittorias rather than the branding.

The 33s are ETRTO 622x33

but the 35s are actually 622x37 and the 38s are 622x40!
IME, the "35s" on a 19mm rim will come up quite a bit wider than 35mm

I was literally about to post on another thread about this. I got some 35s and it turns out they are 622x37 on the side. What gives?
