No less surprising though and a little more than I would have guessed. If we all meet up soon I will bring a scale for the benefit of accuracy.

Is there some sort of bracketry associated with the canister? How/where does it get mounted?

Good idea ditching the dual filter system though. Just seems like added complexity when it's not needed. A lot of things in this thread go hand-in-hand with 'keeping it simple'. I'm always for reducing complexity and redundancy.
