Imo G maulers are better for 1vs1 edge pking, 60 att dds/dscim is better for drag pking or higher lvl wildy pking.
But you can still pk with 60 att at edge and own, your just gonna have a disadvantage imo, because most edge pkers dont have 52 pray, and youll need 52 pray for drag pking(imo). Also if your fighting g maulers, theyll have an even bigger advantage because lower pray+lower att+high hp at lower cmb.
