Acoustic vs Innerforce Layer ALC
Acoustic is the Japanese 5-ply reference: thin, vibrating, high dwell. Innerforce Layer ALC adds inner fibre: more speed, still a round first ball, less of the Acoustic “instrument” feel.


Combined speed 82 vs 86; control 92 vs 88. The bigger gap is construction, not three Combined points. Acoustic Carbon exists if you want the Acoustic family with fibre — that is a closer sibling than Innerforce.
Pick Acoustic if you want wood and Japanese dwell. Pick Innerforce if you want Butterfly fibre with more feel than Viscaria.

Verdict
All-wood Japanese dwell versus inner ALC. Not substitutes. Acoustic Carbon is the in-family fibre step; Innerforce is a brand change.
