An impulse coaster is called such because it repeatedly gets impulses of energy via the LIM's (as opposed to FoF which just gets one shot of energy at the start). It doesn't use "special" LIM's but I'm sure they're continually being improved.
As for question 3, there was a pretty long topic about that a couple of weeks ago. Search function will find it for you.
I know you've been to Japan because seemingly every post you've ever made has to do with mentioning it. Somehow, even if the thread is talking about something entirely different, you find a way to interject it.
However, IMO even if you're infinitely wealthy, if you did what you said you did in your post, you have no life.
I don't know, I rode Wicked Twister, and I didn't think that it was anything overly special. I liked the launch and the twists, but again, nothing that made me say "I wanna ride it again!". I'd rather ride a full-circuit coaster I guess, because it was a walk-on when I was there and I didn't take a second ride.
Of the 3 I've ridden (WT, SFWOA's SUE - yeah I know it's GL now, and SFGAm's V2), I prefer WT. One I'm not crazy about holding brakes and the jerk they give you. Two I love the scenery on WT. Three I like both of the spikes being twisted.
Homey G., if he's anything like me, he boycotts smileys.
Is it me, or do the Japanese coasters have the most hilarious names. Thunder Dolphin is my favorite.
As for the impulses, I've never been on any of the earlier ones with non vertical twists, but no one really speaks highly of that. Of the 3 I have been on, my favorite was Cedar Point's before the tone down. As of now, they are all basically the same, although watching people unaware of the holding break on the one in chicago is hilarious.
Boycotting Dumbii (plural of dumbass) would make living a whole lot harder considering your average joe. Seriously though, lets restrain the vain personal attacks to your American Idol fan club website.
Only been on Wicked Twister and I don't have much of an intention to ride anything else. I love the ride and is my is in my top 5 after TTD, MF, and Raptor. The beach location for the ride makes it very cool and also very cold on a cloudy day.
What is the reason that no other park built another double twister. It is and looks like the better one by far out of the two different types (3 if you count Linear Gale, but what park would want one of those).
