Huss was a much bigger loss, IMO. Multiple quality flats are lacking at almost every major park other than PCW, and Huss was easily the leader in thrilling attractions outside of the Intamin drop towers.
S&S's coaster efforts were iffy. Powderkeg was fun, but not amazing. I've heard wonderful things about Avalanche and J2 is one of the most aggressive wooden coasters I've even been on. The other coasters like the new 4D and Hypersonic opened to rave reviews, but I wonder how Eej will hold up. IMO, Hypersonic has not held up that well at all. Their flat ride selections is rather broad, but most of their offerings are done better by other companies excluding the shot towers. What is exclusive to S&S like the Sky Swatters and the Screamin Swings are plagued with downtime.
I wish the folks at S&S the best, and hope any amusement company doesn't go under, but IMO, the saddest part of this is how their wooden coasters seemed to have just turned the corner and the rug was pulled out from under them.
