I wonder if anyone has thought about anti-anti-tpinning frames
It seems to me that if your opponents front bumper were split in two (as shown on the top side of the diagram below), they might easily "straddle" the side points of your hexagon making it just as hard (maybe harder?) to get out of a T-pin as a straight side would be.
This isn't a critique of your design directly - lots of teams have been experimenting with hexagonal bases recently
