Is it extreme? It’s called perception vs reality, as if they’re trying to say “you perceive it’s bad/too rolly/whatever but it’s notâ€. People that don’t know Radical as a brand can’t have a perception by default. The implication seems clear to me. If their intent isn’t to show that they are better than people think, the videos are very poorly titled.
I’ve had plenty of Radical balls and had a few winners in that lot but mostly was unimpressed. The Jackpot was very good, in particular.
Your interpretation of "perception vs. reality" is interesting. I take it to mean that general perception is that if it's a Storm or EBI oil ball, then, by definition, it's the most hooking ball on the market. Their well financed marketing machines bombard bowlers with that message constantly. Radical, through the power of visualization, is trying to show that reality might actually be different. They're getting lots of attention on message boards, so mission at least partially accomplished.
I personally take the videos as entertainment. There are too many ways to manipulate the videos to take them as absolute gospel, but they are fun to watch.
I also own a lot of Radical balls, and I mostly agree with your overall take. The Jackpots (pearl and solid) are two of my favorite balls. I also really like a few of the Guru's. However, they've also had their share of what I consider duds. They're really no different that the other companies in having a lot of both winners and losers.
