[Zope] BTreeFolder2 disadvantages?

Hello, I was just wondering if there were any disadvantages to choosing to use a BTreeFolder2 as the base class for a product rather than a standard Folder. The object is likely to contain at most a few hundred subobjects, and in many/most cases probably under 100, so the choice probably won't make a big difference. Are there any performace (or other) disadvantages to BTreeFolder2 with a smallish number of subobjects? Or is it always better than a regular Folder? Thanks in advance. Alec Mitchell
