This is worth a new post, I think.
Weighed my heavier limited-legal tracks (and SA165) while playing around with SA165 just now, for comparison's sake. However, I couldn't find my calibration weight, so these are only good for comparing to each other as my scale could be out by a few mg in either direction, so don't go quoting them etc.
Track ___Weight (g)
SA165____6.21
R145_____4.73
GB145____4.54
TH170____4.45
H145_____4.42
M145 ____4.30
SW145___4.28
230______4.16
230______4.16
V145 ____3.92
UW145___3.68
WD145___3.59
ED145____3.56
UW145___3.52
S130_____3.38
C145_____3.15
AD145____2.84
The main thing that surprised me - if perhaps only because I haven't got this stuff memorised from beywiki - is that TH170 is almost exactly the same weight as GB145.
So I did some testing, and also tested SA165 while I was at it, though the attack combo I was using is probably not going to be hurt by SA165 that badly.
I also did some tests. (Also wow I wish Beytest had worked while I was on holiday this is WAY easier than writing this stuff up manually).
RF is worn, but pretty close to prime performance wise, CS is quite rounded, not aggro. Numbers after TH indicate the height it is at.

Redid this because I realised I was using a near mint gravity and a different earth, which I didn't use for my huge test posts.

Gravity had more trouble here than it did against TH170, more than what was reflected in the results, too, I think.

Odd, I always remembered TH195 being best against 145. Perhaps that was only the case when both are tornado stalling or for stamina or something, idk.

This was kinda weird. Earth was murdering Gravity, then Gravity was murdering Earth. Odd and maybe I'll redo them tomorrow or something, as right now I'm starting to ache a lot for some reason.
That's not too bad in terms of how fair SA165 might be (assuming nothing is up with those results), a 10% drop is not that serious. However, from informal testing with other wheels and heights, this gravity combo seems to be among the least affected of the things I've tried, and coupled with RSF it could worsen the troubles of the right spin attack wheels that make up most of the format's legal wheels, as they seem to struggle more than left spin does with it (weight differences do tend to be more of an issue for right spin attack types than left spin ones, in my experience). Also, if we don't ban Gravity, the LAD boost SA165 gives it could be problematic for some defense types (mostly thinking of chrome wheel defense which is already on shaky ground there against R145, but it could also affect certain other things, judging from the couple of OS's gravity r145 managed because of height matchups and spin stealing).
Back to TH170, while GB145 is apparently better against opposing 145 heights, TH170 did seem to be a better choice against CH120/CH145 in informal testing (CH145 worked better but overall still seemed worse off than 120 vs 145). Might test that tomorrow, assuming I am up to it.
