[Product]  BB-41 Beystadium Super Attack Type

In the video, スターター said he had Storm Pegasis 105F, for some reason.

Actually, in a more recent video, he shows a Storm Pegasis that obviously has RF, yet he still calls it F ... Therefore it must have been Storm Pegasis 105RF.
All of the beyblades keep hiting the centre ridge and die.
The stadium doesn't look like it was well designed like Beynval said it's just random.
Most certainly wasn't an RF in that video, the sound and the movement can't have been that far off.

RF should have also moved a lot faster even if it was worn.

Regardless, the SAT looks like garbage based on that movement and performance, at least for F and other attack oriented bottoms.

Perhaps it was designed for B and WB to move around more? From what I saw of Rock Leone and it's B bottom it certainly was able to move around fairly well, even going over that middle ridge.
Guys, he's using a String shooter... He could just be launching incorrectly. It didn't seem like it was launched well to me.
