Thanks for the feedback. We don't want to offer too many choices, as it complicates backward compatibility testing, and want to stick to two options at most.
Since this is the second time I'm seeing this feedback, I'm inclined to reduce the block size for BEST_SPEED in order to trade a bit of compression ratio for better decompression speed. I have some changes to stored fields on my plate, I'll include this change as well.
