We have gone to two NAGA tourneys this year. Have not seen a tranny on the mats and did not know that NAGA was indulging such madness. Their divisioning system has historically been fair and spot on. My daughter is a savage and technically more proficient than my son, although that skill gap is closing. That being said, the boy bests her nowadays due to inherent Y chromosome brute strength. Training is training but I can guarantee you she would flat out refuse to roll with a dude in competition.
