For some random reason, I watch some videos on YouTube showing a "Roller Coaster" built using Lego.
I never enjoy to follow Lego instruction, and I always prefer to build something my own, mixing any Lego bricks from any set.
I only found that set #10261, which wasn't used in the video. But is the only official Lego that I found, but it's too much limited, and I can't imagine built anything rather than the intended build. Buying multiples times the same set (5x #10261) appears too much expensive and still restricted.
I found another non-Lego set, called "CoasterDynamix Roller Coaster Factory", which allows some creativity. However, I can't find it to buy.
What is the recommendation for the track? There's any set like the old "CoasterDynamix Roller Coaster Factory"? Also, since I don't have any brick, what set of random blocks, for the support structure, is better?
