Seems like they went back and fourth to me.
Sierra Sidewinder and Pony Express don't count as family rides, since their height requirement is 48" (well, 42" for Sidewinder with an adult). They might be tame, but the height requirements deter families from being able to ride together.
I think Knott's have done a great job of adding a good mix of both beginner and intermediate rides to complete the influx of thrill rides installed from the mid 90s through 2004. I think the park is due for a real thrill ride, but that may still be a few years off. In the meantime they're doing a good job on focusing on detail and appealing to all ages, which is important. The theme park ecosystem in LA has a pretty specific balance, and all the parks operate knowing their individual place in it. Disneyland appeals to younger children and families, with a few thrill rides for the older kids and adults, Universal caters to families seeking intellectual property rides, but mostly skews to teenagers, and Magic Mountain focuses on coasters. Knotts gets everyone else, as well as a lot of Disney guests seeking an extra park experience. Magic Mountain know they can get away with slacking on park upkeep because the GP will always come ride the coasters. Likewise Knott's know that they exist to cater to people looking for a well rounded old fashioned theme park, so they focus on offering a large variety of rides and keeping the park look nice.
