Recalling that the denominator of the (old) base shear equation is an emperical representation of the framing type's ability to asorb the energy of the design earthquake in the post yield mode. Whenever you are unsure it is best to err on the conservative side and use the lower Rw value which results in a higher design base shear. Even designing with Rw=4 (or Is=1.5) might not be all that off base. The cost of construction will not increase appreciably and you can sleep better.
