I paid for the Premium version for a month and found no difference whatsoever between it and the Basic one, using the chained servers following the guide to set them up actually made it worse. I ended up going with Pingzapper because it seems to give me a bigger improvement.

It does suck that programs like this are basically a requirement to play Ninja well outside of Japan. They really need to revisit Mudras and how they work. I don't know if making Mudras client-side then having them send the combination you entered to the server to do the final Ninjutsu would work, but something needs to be done.
