I didn't test as many Tracks as I figured I would, but ... here's a ton of test results anyways! Unfortunately, I wasn't in the mood to do 20 rounds for each set, so please don't take them as gospel, as they are not going to be terribly accurate. I encourage you all to test it yourself and post your results here when you get one.

This seemed a bit odd to me, so I switched to a R2F and did the tests again:

Same as what Left Spin had with the previous RF ... From here on out, I decided to switch to a brand new, mint RF.

S130 is OK with Vari Ares, but I found that the hits were not as powerful, or rather, the powerful hits weren't as frequent as they were with R145.
Vari Ares R145RF (Right Spin) vs. MF Hell Kerbecs BD145WD
Vari Ares R145RF: 9 wins
MF Hell Kerbecs BD145WD: 1 win

No contest.

CS helped Hell Kerbecs slightly, allowing it to either a) outspin Vari Ares or b) utilize it's recoil to KO Vari Ares.

Along with the results against the BD145CS variant, this was impressive. Despite it not being consistent, the KOs it did score were convincing, some coming late in the battle.
If you extrapolate some of the results, they may not look like much of an improvement over the Vari Ares BD145 results I originally posted, but trust me; like Dani mentioned herself, the three wings of R145 harmonize well with the three-sided Vari Ares. BD145, on the other hand, blocks some of the Smash Attack points, and S130 is OK, but just a bit awkward based on what I've found thus far. And as some members predicted, right-spin is generally better than left-spin (unless it was facing an RS custom, obviously).
