I can see CP choosing the Windseeker over StarFlyer just from a capacity standpoint.  64 vs. 24 passengers per ride cycle is a big difference.  I don't understand the patent infringement case, the rides are significantly different.   Lots of companies have built tower rides and rides with seats on rigid arms that spin in a circle, and swing rides.  I guess they need to sue them to.  Maybe they're just upset they lost the deal.
