I started BIAB about a year ago, and have medaled in a few competitions. Not to brag, but to point out that BIAB is valid.
I think it's more process. QC, sanitation, recipe development, temp control, etc.
I have no problems using the Riptide. Not sure about the abilities of smaller pumps.
You do get the advantage of better temperature control of the mash.
I've just crashed in the Fermonster (7.9 g). It did suck the sides in, but they pop back out with a little pressure, or return to original temp with no ill effects.

Update - I doubled the amount of thread tape I was using, and it seems to have taken care of my NPT leaks. I used Blue Monster thread tape which feels thicker that the normal stuff.
As Broken Crow mentioned, This was an attempt at his version.
I had built your version, but found it finicky to get a seal. If I tighten to much, my silicone washers mush out between the post/nut and the lid. You wouldn't have links to the washers/seals would you?
Thanks, Broken Crow. Since I already have the one from Aliexpress, I'll keep trying to find a way to get a seal on that.
Going forward, tough, I'm thinking Fermzilla. With all the parts, and depending on the model, Its getting comparable in costs. My LHB shop has the older flat bottom for...

Damn, maybe that's it. I bought some from Amazon, but the liquid post has no way to attach a dip tube! What do they expect you to do with that? Mount it at the bottom of your keg?
Anyway, I bought another from Aliexpress. The threads seem to match like any other NPT, but even with tape and...
Sounds more like one opinion. As I said, I've seen sources call a batch what's left in the kettle a batch. It may be a common opinion, but I don't think there's any definitive source that says "normal/typical convention" is what goes into the fermenter is a batch.
