Half Pipe is a fun coaster, but really feels more like a flat ride, it is not too dissimilar from a Pirate Ship or Zamperla Disk-O. What makes the ride fun is the spinning element, but sadly this seems to be rather sporadic, and sometimes the cars do not spin very much at all. This may be down to the fact that the ride had only been open for three days prior to my visit, and it did open late that day due to technical difficulties.
As with most rides that spin randomly (at least it appears random) each ride can differ greatly, this has an advantage that no two rides are usually the same, but it also means that some rides are not as good as others. I rode Half Pipe twice and I sat in the same position each time, but my second ride was far more thrilling than my first.
The ride is quite tame, but can produce some good gs if you are sitting in the right place at the right time, whatever that is I did not ride enough to find out, or maybe it has something to do with weight distribution. I especially enjoyed being launched face forwards to the top of the peak, and then spinning at the top, but this only happened once.
Dispatch times were quite quick for a new ride (about 2 minutes) and the line seemed to move quite quickly. I think Half Pipe is a good ride, and packs a good punch for its size. It would be nice if they could get it to spin more, and build the next generation of the ride a little higher, as 100-feet is not very high by todays standards.
