My opinion is, none of the above. The Score is a large, draggy airplane in addition to being heavy. Mine is in the 72 ounce range and powered by a Saito .56. It has good, reliable power, but definitely isn't over powered. I am not familiar with the ASP .61 but it can't be any heavier than the Saito. The Score has a fairly short nose and can stand the extra weight, just a matter of knowing if you can get the run you want out of the ASP??
