True, if it's not mostly twistes, then the accleration would win out most of the time. Although, if speeds stay below 110 - 120 then the Spyder does pretty good.
The Dragon is in NC and TN on US129. It's not far from Memphis or Tuscaloosa for that matter. It's about 40 minutes from Knoxville. I think you would enjoy running it a few times, it really is fun. I can let you know when the date is finalized if you think you might want to come.
