As far as making tweaks, yes, no matter what brand, a thin profile neck will always require by and large more regular adjustment then reinforced ones. Lightwave Systems/Willcox Guitars makes maybe the thinnest neck front to back I've ever owned, and it did require me to touch it more then say my Kubicki Ex-Factor. They key is that it is adjustable and you can dial it in to where you want it with no issues.
As a former label signed bassist who has toured the world, why do you think we all have our own tour techs? Because sometimes, even during a show, you need to make adjustments because of where and how you are playing. There was a thread over on the Fodera Club that talked about a particular Fodera that had a neck that needed more adjustments then the player was used to with his Fender. Well, that does happen. The key is that it is adjustable and you can keep it playable.
I also want to point out, as most of you are saying here, you guys are looking for super low action with minimal regular adjustments, which in my personal experience is not the case. Now I am a person who learned to play in the 1960's, and what I call low action for all of you would be super high action (20-30 thousandths at the 8th fret) so I need to adjust the neck much less frequently. If you read the bass maintenance article done by Roger Sadowsky about ten years ago he talks about how Will Lee has actually moved to slightly higher action over the years, and I am sure in part it is due to being able to not have to constantly adjust the neck before playing it.
Either way, pretty darn amazing that you can have a bass at the price point of a Brubaker Brute that you can dial in super low action in most cases.
