All great manufactures. I love Schwarzkopf for their lap bars, B&M for the smoothness and their innovative concepts, Arrow will always a special place in my heart, Vekoma....um, they make... ...roller coasters.
Which leaves Intamin. If I had to come up with a top 5 list of steel coasters, I don't think they would make the cut. However, they're still my favorite. Logic need not apply.
