I agree Dan. A standard must be maintained. you are not going to get the hundreds of users that already own the TBU to accept a system that can limit their abillity to inflict damage at a ratio that is out side the norm for the TBU.
Tim has a point that any club has a right to use whatever system they want, BUT if you want to compete in sanctioned formal competitions that have established rules and requirements then this system may not be admissable with some of the adjustable features.
I on the other hand feel that the 45 degree defense needs to go and Tamiya needs to adress this.
