Both are Butterfly blades built around feel, but they target different stages of a player’s journey. The Innerforce Layer ALC keeps an all-wood feel and dwell up close, then delivers a carbon kick and OFF speed on hard swings, with a large, stable sweet spot. The Primorac is a classic all-wood Limba-Limba-Ayous-Limba-Limba build with long dwell and outstanding control, forgiving and easy to play but limited at the top end.

Pick the Innerforce Layer ALC if you want all-wood feel plus on-demand acceleration and a higher speed ceiling, and you have a developed stroke. Pick the Primorac if you are a developing intermediate or control-first all-rounder building a first serious custom setup and value feel, dwell and spin over outright speed.

The Primorac can feel underpowered with the modern plastic ball and is often outgrown as a player improves; the ALC carries more pace and stability. The Primorac is the durable, forgiving classic, and worth confirming you are not buying the much faster Primorac Carbon by mistake.
