Teach me about the FAL

[Failure2Stop]

FAL Gurus-

I am looking for in-depth knowledge about the FAL.
I did a search but the three-letter search was less than helpful and the existing FAL Info thread doesn't really contain the knowledge I am looking for.
If there are existing threads or outside resources/forums I would be happy if a link is provided.

I am considering purchasing a FAL for personal use and after chiming in on another thread I became very aware of how little I really know about the platform.
Templar brought up concerns about the shortened gas system, and while I am not at all doubtful about the advised aversion, I would like to really understand the "why" about it. I want to know the little intracasies and details of the platform. I don't intend on this becoming the be all and end all information source, but it would be nice to have a source for that info.

Thanks.

ETA- I just registered over at the FAL Files Forums, but if there are other places/people that are outside that community and it's stickies, please let me know.
