I really don't know. There's quite a number of things happening at once in the block I have, and it's not entirely intuitive with even a moderate understanding of what's going on.

As you drop down the channel width you'll also need to decrease the fin width. As you decrease the fin width you'll also find that you need less fin height. As you decrease the fin width and height you'll start to sacrifice structural integrity. You'll also have increased water resistance. Also the "play" of the nozzles will be affected quite significantly.

In short, it's not as simple as merely dropping the channel width and hoping it'll be better. There's a lot of complex interactions and geometry going on, including the all important structural considerations.
