I know I have less than 10 posts here but that does not mean I know nothing. The track pieces that have been posted here are indeed for a Wing Coaster (where....we do not know but some have been saying that track is a dive coaster which it is definitely not) Following the "WI" on the track label is the letter "G" which represents the 7th Wing Coaster (Gatekeeper was F and FOTR was E). For those that are hoping for an inverted coaster, if the label says "IC2", the track is for an invert (they use the 2 because they ran out of letters to use; they also skip some letters because some look close to numbers). Finally, a giga (or hyper) would have to have the code "MC" in it.
I know most of this has been mentioned but some seem to be ignoring what people are saying which is true.
Oh, and that yellow track being talked about above went to China. http://rcdb.com/9647.htm
