it doesn't matter the size, density of glass is the same regardless of the size of the glass (density compared to water is what makes things sink or float in water). if the glass has a higher specific gravity than your wort it will sink regardless of its size (in theory). but small pieces would be easier to stir up from the bottom.
if this was me i would rack always holding my siphon a few inches above the bottom, and leave a little bit behind, and then rack to a secondary to be safer. and then rack to a bottling bucket, and then into bottles, and just pour every bottle into a glass before you drink it and just be aware!
just out of curiosity what did you end up doing?
