Here is a draft cc list I made while doing testing on parts for the format back when it was a tiny private project (hence some prospective notes like "if RS is illegal" etc). Keep in mind I lack anything from Zero G aside from Revizer, Dragooon, Saramanda, Samurai, E230 and SA165, I don't have any Metal Fury and I also lack Cloud, Crash, Divine, Forbidden, TR145, SWD, and I didn't try Bakushin because mine is an eclipse ver and I had it in a box under my bed (or MB and W2D for stamina as I never got around to that), so they aren't accounted for at all by this. Basically: I'm just posting this as a starting point for discussion, the list in general, and also because it has some tips on good benchmark combos etc.Faces: MF-H's seem to be the best choice for attack and defense, regular faces for stamina but don't be afraid to experiment there or anywhere really (MF-M seems to provide better stability for stamina types which can be helpful for spin stealing matchups and various other things for example). I assume metal stone faces are the same but I don't own any.Attack:MF-H Gravity Perseus (ATK>DEF) 85/90/CH120/D125/R145/TH170 RF/R2F/LRFMF-H Lightning L Drago 85/CH120/R145 RF/LRFMF-H Leone 85/90/CH120/R145 RF/R2F (TH170 might be an option).MF-H Pegasis 85/90/R145 RF/R2FMF-H Screw Pisces/Horogium/Uranus 85/90/R145 RF/R2FMF-H Ray Kerbecs/Unicorno II/Unicorno/Whatever 85/90/R145 RF/R2F (borderline)If RS is illegal, Vulcan and Quetz also get a spot, with low tracks, CH120S and GB145 being the best choices (GB145 in particular for quetz, Vulcan really prefers being under things/low tracks in general and doesn't work well on tall tracks at least from what I've tried (which matches what I remember from back in the day).)Notes:Yes, Screw and maybe even Ray work better than Vulcan, mostly because Vulcan isn't very good in same-height matchups or against lower opponents or on tall tracks in general really, and also doesn't have good synergy with R145 which seems to be a big deal. I've tried old and new ones, it does work very well on low tracks vs 145 defense, however given LTDC will be a thing and that lightning does better against them, it just seems kinda inferior to lightning.Gravity, Lightning and Leone are good for benchmarking.On Tracks: R145 seems to be the best choice in general by a significant margin, weight (and ability to put it right under contact points) and some ability to handle lower opponents is extremely useful.GB145 seems to be the best option for two-sided attackers.85 has use on lightning for doing well against LTDC, and on Gravity for OSing libra LTDC.CH120/D125 might work on more than Gravity/Lightning but I haven't really tested anything else with those tracks yet. The same goes for TH170 but gravity benefits more significantly by being able to OS Earth 85RF/RSF (but not RS). Have only tried leone as an alternative though, so others might work (screw perhaps?)SW145, UW145, H145 might be viable, but I've had no luck with H145 and the others have to contend with R145 for a spot so eh.Metal Flat ends up making things too balancey seeing as there's nothing like flash here.Defense/Anti-AttackClear Wheels are the same as regular MFBMF-H Earth ___ 85/90/GB145/TH170/230 CS/MF/RSF/RFMF-H Libra ____ 85/90/GB145 CS/MF/RSF/RFMF-H Flame ____ 230/TH170??? CS/MF/RSF (borderline, RF seems like a bad idea)MSF-H Reviser ____ 85/90/GB145/TH170/230 CS/MF/RSF (RF will get you outspun by a lot of things)Notes:Earth and Libra are the best wheels to use for benchmarking as Flame is situational/limited to tall tracks and Reviser has its balance issues. CS and RSF are generally the best choices for tips for benchmarking, particularly RSF given CS's variability. RF/MF move too much to be truly consistent.Stamina:I don't have SWD, and haven't tried W2D and MB. They would likely be competitive I guess (MB is a maybe, and only on tall tracks). I don't have any Zero G tracks/tips that are legal, either.Earth ____ 85/90/AD145/TH170/230 D/SD/WD/EWDBurn ____ 85/90/AD145/TH170/230 D/SD/WD/EWDVirgo _____ 85/90/AD145/TH170/230 D/SD/WD/EWDLibra 85/90 D/EWD/SD/EDS? (Libra is only here because it can take hits well and has okay stamina, so it's more balancey)MLD Spinstealers are probably going to have some place too, though earth could pose a problem for them if I remember things correctly.Thermal might be worth trying as some people had success with it, but I was very much not one of them.Notes: Earth and Burn are standard, gold standard for stamina v stamina tests on metal wheels used to be putting both on 145WD and making sure the WD's were both at least near mint so that still stands I guess. Virgo is probably not great to test against because of the whole mold thing.Balance:Haven't tried anything serious yet, presumably Gravity CH120MF, MLD CH120XF, and various other things would work. MF-M Rock Cancer 85/90MF is cool to mess around with, but almost certainly not competitive. 230MB combos could go here, perhaps. LDrago 85MF might be usable etc, MLD CH120XF will work, and maybe some things with libra, idk. Attack dominance and no RDF should prevent anything too powerful in balance though, at least not anything that doesn't show up as broken for another type. Oh, F230 will be there so there's that and CF/GCF might also be exploitable some other way but yeah.
