I'm curious to see how that Konstantinovs-style works for you. Funny, I just watched those videos the other day when you posted them on the "Thread of Physical Awesomeness" but I didn't notice his unique style until re-watching them.
And regarding the box, I enjoy using one, it really helps regulate depth which is a nice advantage.
