Okay, after probably 7 or 8 rides on Steel Taipan on the trip (will probably do a trip report at some point), I'm definitely a fan. Second favourite coaster in the GC, just behind DC Rivals - and that's only really because they're different types of coaster. DC Rivals is all about speed and airtime whereas Steel Taipan is about the elements.
We did also try the tailwhip which was damn good fun, a lot better than DC Rivals backwards. The barrel roll at the end, while spinning, and hanging on the first incline the coaster goes over, are pretty damn good.
Queues are very low - through the trip we never waited more than 15 minutes, compared to DC Rivals posting 70+ minutes.
