At 6'3"+, I have never seen a provider who was taller than myself (Although that certainly intrigues me). Orchids, although tall, is a slippery, nimble little thing in my book, and about as athletic as they come. I don't doubt she can spin.
I have been with a few providers (and other girls), who fit the 5' 105 lb description, and generally I am afraid I may accidentally hurt them.
