Both are 5-ply all-wood blades, but the Infinity VPS V is faster and firmer. The Primorac is OFF-minus, 85g, soft-feeling with long dwell, high control and broad rubber versatility. The Infinity VPS V is an OFF blade, 88g, with a stiff thin outer from its VPS and Diamond Touch construction, flex and dwell that reward heavy brush looping, many gears and strong stability.

The Infinity offers more power in the fast game while keeping control in the short game, but it gives up a little to carbon blades from well behind the table and ships fairly raw, needing the thin outer veneer sealed. The Primorac is the more forgiving, easy-to-play classic with a lower top-end speed that ambitious players outgrow.

Developing intermediates and control-first all-rounders who value feel and forgiveness should take the Primorac. Dynamic, spin-first offensive players who want a controllable all-wood OFF blade with many gears for heavy brush looping near to mid-table, and who do not mind sealing the veneer, should take the Infinity VPS V.

The Infinity VPS V. Its flex and dwell reward heavy brush looping with a medium arc and it offers many gears, while the Primorac rewards spin and placement but at a lower OFF-minus speed.

Which is faster?

The Infinity VPS V is an OFF blade with more power in the fast game, against the Primorac’s OFF-minus. The Infinity still gives up a little power to carbon blades from well behind the table.

Does either blade need sealing?

Both benefit from it. The Infinity VPS V ships fairly raw with a thin outer veneer that needs sealing, and the Primorac needs to be sealed to prevent wood chips when changing rubbers.
