This question is mostly just being driven by my curiosity. I know that burning 100% corn requires special venting material. If one burns a 50/50 combination of wood pellets and corn, does one still need more expensive corn-rated venting?

The special venting is required because burning corn produces products that are corrosive, burning a mixture just produces a smaller amount it doesn't prevent it from forming so the answer is yes.
The manual says PL or L venting is to be used. It however is silent on what gets used when.
PL vent pipe is rated for both wood pellets and grain (corn), type L is rated for wood pellets.
So as they say pick your poison, my bet is the PL will stand up a lot better than the L when burning any quantity of corn. I wish I could remember where I saw a picture of some vent pipe after being used with corn that wasn't rated for it Holey would be the word I'd use to describe it.
