About this club

Lamkin's Crossline Black is Sub 70's house grip on its tour builds. The 649 MB Tour wears it. Underneath sits a one piece DT-4 forging with a 34 degree 7-iron, sold 4-PW in right hand only, with flexes from senior to X-stiff. Shafts get specified when the order goes in, drawn from a free list that runs well past what a normal stock menu would offer, so there's no single default to name.

Muscle backs at traditional lofts are a shrinking category and Sub 70 keeps two of them. The 649 MB TR Forged matches this set degree for degree and differs in dress rather than design. Anyone playing full blades already knows what they want. Everyone else should be blending these into a cavity back long iron and stopping around the 6.
