FISTF has announced some changes to the rules. This is the first change in over five years, and are to be used going forward.
FISTF rules (version 5.0) can be found here.
Some explanatory notes on the changes can be found here.
I do know there will be some questions, concerns, and possible confusion, but I, along with the rest of the Board of Directors, are here to answer any questions that you may have.
