Some is program dependent.
If I'm at a lesser one, say Cal, I'm running the triple. Probably a flexion variation.
If I'm at a bigger school, I'm running whatever we call Dan Mullin's offense. I guess it's a run spread, but it's versatile.
I can't logically run the single wing as a primary college offense, but I'd want to. All that said, Wisconsin should only run what it does now, which is run-heavy, I and double tight wing, with a passing game that spends a little time in the gun. It's interestingly a whole offense that runs off run-run-pass and remains effective.
