Converting an extract recipe to BIAB

[OneDogBrewing]

I'm trying to figure out how much flaked maize (or other suggestion) to substitute in a BIAB version of an extract recipe that calls for 8oz of corn sugar.

The recipe also call for 8oz of rice solids, but I'm thinking I can keep that?

Basically looking to create a BIAB version of BB American Light, (which I've brewed maybe 5 times over the years, but want to evolve, starting with a BIAB version)

There's no need to change the corn sugar in the BIAB recipe. It's a simple sugar and pretty much will just raise the OG and increase the wort fermentability. You can substitute regular table sugar and you'll never tell the difference except in the cost.

For 8 ounces of corn sugar, use about 9 ounces of flaked corn. Corn sugar contains 96% fermenter sugar, while mashed corn has about 84%.

Reference: "How to Brew" by John Palmer. Some information is a little dated, but there is a lot of good reference info.

Both of those answers are the right answer!
Sugar is sugar, whether from mashing flaked corn or using the sugar. Whatever works for you is best.
