Hi Daniel, It turns out I just didn't fully understand the n-bit types and filters yet. The bit types always store in bytes in but then the filter will pack things further on read/write. So I got what I wanted working with bytes in memory but bits on disk for bool data sets. Thanks again for your suggestions.
