[member=79984]HighlandMarine[/member] – since you already have the FS-WA and -VL extension you are also familiar with TSO’s patented method of connecting that system quickly and securely to the guide rail.
The difference for squaring with a GRS-16 PE lies in the fact that, by design, the “square” function is machined out of one solid piece with. No part assembly tolerances trying to add up to 90 degrees.
How often do you need to cut sheet goods at angles other than 90 degrees? – if it is infrequent, you will likely find the GRS-16 PE a simply unbeatable everyday companion – literally.
...
To add as I understand you will not want to raise the limitations of your product ..
The main disadvantage /which Festool does not mention, in turn/ is that:
- The FS-WA
MUST be calibrated after every angle (or rail) change against a known-good square to achieve anywhere near the precision the GRS-16 (FS-WA/90 in Europe) provides. The "dents" are only approximate there when cabinetry precision is needed, especialy for melamine stuff and the like.
but then, the benefit is
- The FS-WA
CAN be calibrated
as a complete assembly with the rail so (the back of) the rail not being absolutely co-linear with the saw reference edge /which limits the GRS-16 practical precision/ becomes a non-issue with the FS-WA.
What that translates:
FS-WA is absolutely brilliant for no-holds-bared precision
when one calibrates it along with the rail using a known-good reference square.
On the other hand, the GRS-16 is absolutely brilliant for quick&easy square cuts *when one knows* the rail's back is absolutely straight*) or one is OK with a bit of imprecission from the rail backs not being all absolutely same.

Wondering if anyone can share their experience with using the angle stop or grs system to square tracks to the workpiece. ...
Given you are mobile, here would be my approach:
(1) Look at the MTR-X for mobility and upgrade to MTR18 only after/if you find that one too small for your needs. The MTR-X is an excellent combo with the FS-WA considering the flexibility and calibration needs of the FS-WA. MTR-X is big-enough for 90% use cases, so even getting both eventually is not a money waster long term, should you find wanting something bigger.
(2) Seriously look at the TSO Parallel Guide system, in short: You. Want. That. Thing. Relating to that try avoiding the GRS-16 at this stage to save on the mounting s for the PGS. While the GRS-18 can be used with the PGS, it just makes the whole setup heavier and more cumbersome than necessary.
(3) Bases being covered, look into the GRS-16 as a "speed improver" if you find yourself needing. It does *not* provide a different function to the FS-WA and MTR-X combo, so it does not improve capability, but it does allow the most common square cuts to be done faster/simpler.
IMNSHO the (2) TSO PGS is a way way bigger game changer than the GRS-16 is and you absolutely require (1) some form of a reference square for using the FS-WA with precision. Were you in Europe, I would direct you to get something like a $50 DIN Class 1 reference square first, but in US these "middle precision" things are unobtainium. Going for a $300 Starret would be a waste given the MTR-X is out there and provides many more functions for the price.

Disclosure:
I have 2x GRS16 and 1xFS-WA which I set up with a down to 0.001" precise engineer's square for square cutting.
Since I got it to complement my GRS-16, I ended up preferrin the FS-WA over the GRS-16s for longer cuts - it is more reliable when the rail back not absolutely straight.
I still prefer the GRS16 for short square cuts, under 15", where it is just unbeatably quick and the precision is adequate even with a non-ideal rail.
