Here is how the dual format will work.
The event will be run as two separate tournaments with the normal entry fee and big fish option. You can fish one region or both regions if you wish. You will need to declare which region your fishing in at check in. If you decide you want to count your weight towards AOY and the TOC in both regions then you will need to enter both tournaments. If you decide to enter both tournaments then the entry will be double. You can also just enter the big fish option for either or both regions but you will not get points for the region you are only fishing big fish option.
Fees are as follows: $20 entry and $5 per day big fish option, per region.

Also rule #9 applies to two different organizations holding tournaments but since this is only a BNT event we are not breaking any rules.
