Not all declarations of "fact" are true. One of those is the "fact" that you can go from an 8k to a Jnat. Sure, you CAN do it, but I certainly don't consider it to be ideal. Regardless of the many Jnats I have tried, I have always preferred to use an intermediate between them. With that intermediate stone, I can get to the sticky feeling on the Jnat pretty quickly. I can get there without the intermediate, but it takes a lot longer.
