So,
Thus far it's been a good journey.
It is worth the effort.
All I've had is SFS systems light density dark brown 5% white with body wave.
I get them cut-in by Maria in Chicago. The cut in is huge. Don't do it yourself unless you know what you're doing.
The best glue for perimeter/full head bond etc is Ghost Bond. Easy to clean-up. Holds like nails.
The best tape depends on chemistry of person. Proflex or supertape variants are a good bet.
The last 2 attachemnts I just did with tape full perimeter.
The front has a bit of shine but it goes away after you sleep and take shower.
I like to use a strip of tape down the middle for stability. I could de/re every 2 weeks but I've been doing it every 10 days or so just to feel clean.

One thing I noticed. When I take a shower and shampoo, the tapes hold good. When I use conditioner though, I compromise the long term bond. The right thing for me is to spray the conditioner/water after I shower.
Conditioner has this unique ability to "lubricate" all the nooks and cranies and make it through the edges of the tape.

I decided to take this route (hair system) while I still had hair on top. I just could not hide my bald spot/receeding hairline anymore. . .
Actually, I wish I did this 2 years ago.

So far . . . nobody knows I did this. I know they are not "being nice" etc.
There are no stares or glancing at the hairline etc. They are freaking clueless. For real.
I forget I have one on myself.

I started with a very light density piece (could see lotsa scalp). This compelled me to use glues.
My new system is denser now. I can wear tapes and get away with it.

Anyway,
Thanks for all the help here on forum.

My next adventure is to try the TL700.
