Forum:Berserking or Beast Rising?

I'm in a bit of a quandary, here; I've got a Weenie Beast deck that used Berserking as a major source of ATK, but now with Beast Rising coming out, I'm torn on which card would be better. Thus far, here's the results of my comparison of the two:

Timing: Berserking only activates during player's Main Phase or opponent's Battle Phase; Beast Rising activates at any time except damage calculation.

Cost: Berserking has no cost, both monsters remain on the field; Beast Rising requires removing a monster from play to activate.

ATK Boost Permanency: Berserking only lasts to the end of the turn; Beast Rising is permanent, even if it's removed from the field.

ATK Boost Amount: Half the ATK for Berserking; Full amount for Beast Rising.

Original or Current ATK: Current for Berserking; Original (seriously? I thought it was Current for the Japanese version) for Beast Rising.

Other Amenities: Berserking lets you steal ATK from the opponent's monsters; None for Beast Rising.

So, that's three points for Berserking (in cost, original vs. current ATK, and amenities) and three points for Beast Rising (in timing, ATK boost permanency, and ATK boost amount). I'm not able to come up with a good idea of which would be better suited for this deck, so what would you suggest?
