Onslaught mass index

So on demarini’s website has a mass index scale with each model bat listed. The

twisted mistress being the highest (most EL). The DB naut was next then EL naut, then the Midland stuff. However the onslaught wasnt listed anywhere.

Does anyone know what its EL is exactly? I’m interested in it and the twisted mistress but would like to know the onslaughts EL before making a final decision.
