FCS describes the AM as Al Merrick's shaper template designed for radical, progressive surfing, with raked side fins that produce exceptional speed and drive. The Performance Core AirCore version uses a lightweight core to cut swing weight without changing the template.

Blitz Surf Shop's guide to the FCS 2 AM range covers how the AM sits against the AM2 and AM3 variants, which change rake and area for different turning styles on the same family of templates.

Pros & cons
  • Raked side template produces drive and hold through long turns
  • AirCore construction keeps the set light for its size
  • Rated 5.0 out of 5 from 12 verified reviews on the FCS listing
  • Widely stocked template with well-published dimensions
  • Rake favours drawn-out arcs over tight, pivot-style turns
  • $155 sits at the upper end of thruster sets
  • Two sizes only — riders outside the published weight bands must compromise

How it surfs

The AM's defining trait is rake. It rewards surfers who draw longer lines and lean on the fin through a carve, and gives less immediate release than a smaller, more upright template. Surfers who want quicker pivot in the pocket should compare it with the AM2 or an upright thruster set before committing.
