I chanced upon a new set of these heads.  I know they fall into the super game improvement category, but wonder how they would stack up against the STi2 Gen 2 in terms of playability.  I suspect the latter are a good bit more forgiving, but there’s something nostalgic about the MO-6 that draws me to them.  I have a set of new STi2 Gen 2 heads as well and am pondering which set to make up for a Spring project.  Any comments welcome.
