Wow, not much notifications on this one, probably might have more people commenting once it is released on the 27th.
From the looks of it, WzFf Sen Layer might be the best spin equalizer due to its shape being reminiscent of dF which is not aggressive but can easily Burst opposite spins with the correct launch angle and force early on. I really doubt its viability against same spin, unless Rise is actually almost as tall as Volcanic or Revolve at least (to avoid being hit consistently on the Layer). That also goes without saying that it is currently possibly going to be the strongest left spin equalizer on the meta, replacing dF and Sr as being the most circular spin steal Beys.
Off topic: I've been thinking that possibly we won't have a Longinus GT Bey since Ace Dragon has already taken on the "Dragon Attack" category, albeit being a right spin; that, plus the fact that they'll have to pump Longinus' (unnamed) Base with lots of metal since that was the primary gimmick of it since L2, which will cause lots of strain for the existing Launchers released for them to launch the said Bey especially on tankier combos.
