Homebrewers - Whats in the fermenter?

[cobra03]

I have a bottling related question. Im about to bottle my second batch and got my hands on a bunch of 1 liter glass fliptop bottles.these glass bottles are bigger than the liter plastic bottles the kit came with. Now my set up makes exactly 8 liters of beer in the plastic bottles with almost nothing left. Should i A. fill up the glass bottles and adujust the priming sugar making fewer bottles or B. make the full 8 bottles with less beer in each bottle. i would prefer to have 8 bottles but im not sure if the extra air space would cause any issues with carbonation or oxidation. any suggestions?
