The PLD Milled Oslo is a high-MOI mallet from Ping's premium PLD (Putting Lab Design) line, fully machined from 303 stainless steel for a solid, premium feel. Heel-and-toe tungsten weighting and perimeter weighting boost stability, while a light aluminium hosel keeps CG low. A deep face-milling pattern gives soft-but-responsive feedback. Offered in slight-arc and stronger-arc hosel options, with counterbalance and long builds.
