I know that the cores are different in the 13lb equipment, the high end stuff for sure, but my question is this-if i were to get my wife say a-delta 1, 13lbs. with the different core, will it have the same characteristics as the 15lber's? for that matter. would all the high end 13lb stuff have the same shape, oil handling all that good stuff as the 15's? lmk. thanks in advance.
