if you want something with great edge hold, max pop, and butterability at ur weight I would go with the THall. If you want something with max butterability, less pop, and less edge hold, go with the Alpha 1. i wouldn't look at the AR7, as you weigh very little, and for you the THALL will do everything that you would buy the AR7 for just as well, and be much more butterable and playful.
