Hi ; I like the descriptions of offense sub styles in this
guide, I think they can help you (mention screens for HO, and I believe that double switches belong more to standard offenses). Also I think Bulky Offenses pretty much died in gen 5, haven't even tried to build one but i don't remember seeing one in tournaments. You can specify spike stacking offenses as well (the guide put them in Standard offense), although they are rare in OU since Deo D's ban.
