Wtf. No it would not be a fitting replacement for a full circuit inverting coaster. Full Circuit>Shuttle. Never will an intamin impulse be better than a premier spaghetti bowl.
The Premier spaghetti bowl isn't that great unless it's in the dark like Flight of Fear. Not only is the Intamin launch much better but you get a real drop.
Yeah, spaghetti bowls are good, but definitely prefer the impulse coasters I've been on. Also, Six Flags America doesn't even have a shuttle coaster, so it would fill another important spot in their lineup while still having a launched coaster. I didn't bother responding right away because the full circuit>shuttle comment just broke my brain. Yeah, let's replace all the impulse coasters with kiddie coasters and Pinfari loopers!
They can even bring back the Two Face theme.
If you take the GP into consideration, nobody is going to want to ride a rollercoaster that launches forwards and backwards several times. It's super repetitive and has no major gimmick to it like a 100 mph launch or 400 ft spike.
