@Rai: the stadium doesn't affect wheels that drastically. Variares is never going to be good for anything but attack, the weight distribution is terrible, it's too light and the recoil too high for anything else.
"Logic" always applies, as long as you use the correct parameters.
@Stevebak: I believe that was me, who didn't ridicule you but rather pointed out that it would likely be inconsistent, which it probably will. I'm still more interested in normal mode, but because our knowledge has changed my opinion on ubm has shifted slightly (this is called learning, you should try it some time, seriously.)
As for CF, look at the tests that are already right in front of you... Apparently it does quite well. There are huge differences between CF and BD145, one's a perfect circle, the other has three large spikes that interrupt it's shape and scrape on the stadium floor. BD145 is also far larger, which further affects how it reacts on touching the floor.
Furthermore, CF doesn't really need much control, it's not aiming to hit the opponent, but to move the stadium, and it seems, from initial tests, to do decently well at that, which is what I was referring to. However, were the videos you watched done with stock Chrome/Crystal wheel setups? If so, the lack of control and stamina is almost certainly due more to the balance issues the uneven MW's cause.
"Controlled" is the last word I'd use to describe F: D, especially when it shifts to attack mode. The part has always been a poor idea, as it's the wrong way around: Rubber isn't good at the end of a battle, when you've lost the energy as well as not being controlled from the launch. SF isn't great at the start of a battle because it's too easily pushed around and wastes the higher energy. Yes, that could change in Zero-G, but we were talking about F: S, not F: D, and my issue was not even with the tip, but the wheel you chose to suggest: Variares has some of the poorest stamina/defense of any wheel in MFB history. Not just 4D. It literally has NOTHING but attack. To suggest it defend at all is simply ludicrous. Diablo would have been a much more sensible suggestion for F: S, given it's actually an attack/defense wheel, but generally a mode change late in the battle isn't going to help much for something with such poor stamina anyway, and generally auto-change parts have almost always been pretty pointless, aside from a few exceptions. Manual Change parts are generally much more useful, and X: D is a manual change F: S with a shape that *might* work better in Zero-G Stadia.
Of course, we know now that F: S just doesn't work at all well.
Now, everyone, I know you're excited and it's new, and sorry for being a downer, however, I want to get this format sorted so you can actually play with it as soon as possible, and sadly, that means I'm not comfortable with 'wasteful' requests.
"It's a new stadium" is not a valid catch-all cry for requesting tests of ridiculous combinations. A swaying stadium doesn't change the laws of physics, and doesn't generally affect the properties of most wheels all that much. Furthermore, there is still plenty of logic to be had, just because we haven't explained it all doesn't mean it's not there. We have a vague idea already of the criteria required for success in Zero-G, so apply that before you request things, justify them when you do, and if someone explains why it's a terrible idea, instead of protesting, consider the fact they might actually be right. Nothing wrong with protesting once you've considered that, but you have to have good reasons, better reasons than "its a new stadium so how can you say what will work".
