whats the diffrence, or just a new name, same thing??
its just the new series of slam bags, but the RE is better then the old RS
hold more PSI, more durable, better all around bag, and cheaper of coarse!!!
More durable rubber on the new RE line . RS are the old ones .
They have changed the rubber compound so they wont crack as easy.
do they have an exchange where u can send them your old bag, for the new one or no =) or anything in resending a bag if it tore?
