I never got to ride Goliath. I didn't miss much, from what I hear. Hopefully, SFNE trashes the other boomerang and drops a new coaster where they both used to be!
I always found it funny how they had 2 Boomerangs right next to each other. The other Boomerang is Flashback, which was relocated from Kentucky Kingdom in 2000 and replaced an Arrow shuttle loop called Black Widow. That's the only launch coaster SFNE has ever had. Flashback actually dates back to 1985, because before Kentucky Kingdom, it operated somewhere in China. I think it should be removed because it has to be nearing expiration date.
Goliath came from Six Flags Magic Mountain, where it originally opened as Deja Vu in 2001. It was moved to SFNE in 2012, where it replaced a shoot the chute type water ride. Unfortunately, it did not have a successful career at SFNE. The original Vekoma train provided a smooth ride, but the park thought the staggered seating was confusing to guests, so they ordered a new train from Premier Rides with regular 4 across seating. That train did not ride very well, and turned the coaster into an uncomfortable, jackhammering mess. The ride was also constantly breaking down and couldn't run in any rain at all, nor temps below 60 degress (both of which are very common in New England).
SFNE gets old quick since it lacks depth. The fall off after the RMC and Superman is pretty steep, and operations on many of the coasters are really slow.
SFNE is definitely "top-heavy". It's a problem at a lot of parks. They rely so much on their top tier attractions and lack depth. In case you didn't know, Six Flags went through a corporate merger back in the 90's with Premier Parks. The pre-merger Six Flags parks tend to be better than the pre-merger Premier parks, because their lineups have more depth to them. SFNE happens to be an ex-Premier park. Take Six Flags Over Georgia for instance, a pre-merger Six Flags park, which serves a similar market in terms of population. They also have a hyper + RMC top two with Goliath and Twisted Cyclone. But below that, they have a Batman The Ride clone, which is better than anything at SFNE other than their top 2. They also have 2 other B&Ms in Superman Ultimate Flight, a flying coaster, and Georgia Scorcher, a stand-up coaster. They also have a Schwartzkopf looper in Riddler Mindbender, and a Gerstlauer Eurofighter in Dare Devil Dive. While their top two isn't quite as strong as SFNE, their lineup has a lot more depth. I actually think it's harder to build a park that has depth to its lineup than getting a one two punch of elite coasters.
