I thought that, too, but someone (forget who) asked or suggested that more than one could be done. With the Maximatic's higher flow (than a MAV-2), I'm willing to bench-test it. After all, it'll only take changing some plumbing on one of my fast-gun ships to test. If it's a bust, we have data in hand verifying the conventional wisdom, and I'm not out any money.
I'm in the ER tomorrow, so it'll likely be Saturday before I get out in the shop to work on boat stuff.
