Nothing... the Sync is a particle solid asym and I don't even think Hammer has had a particle ball in their lineup since the Big Blue. I would agree as above that the Amp would be their oiler but Hammer doesn't do a real Heavy Oil piece like the Sync. No disrespect to Hammer as they have balls that hook, However, The Sync is a Particle solid asym with an extremely high INT Diff. Hammer doesn't have anything comparable.
