with all respect Stince, these rules have long been in effect. I have no preference over one system too another but a club sets a system parameter and they must be compliant to not provide an unfair advantage over other systems. Our club as many others do use the TBU as the standard. We do not however bar or disqualify any type battle system as long as they perform to a minimum of that TBU. <div> With the SLU currently not being compliant because of the 25% drop off. </div><div>If this can be changed then most clubs will almost certainly accept it as ours would.</div>
