The Fin
The Greenough 4-A as a 2+1 combo — George Greenough's all-round centre fin sold with a pair of True Ames side bites, Futures compatible.
A matched three-fin set in solid fiberglass, in smoke. The centre fin comes in 6.5", 7.0" and 7.5", the side bites in 3.25" and 3.7". The 4-A is the best known single fin True Ames builds, and the balance that made its name carries straight into a 2+1 setup: a full base for drive off the bottom, and a tapering, moderately flexible tip that keeps the fin responsive through an arcing turn. Other size and colour combinations can be had by buying a centre fin and a set of side bites separately.
How that reads
In a 2+1 the centre fin sets the character of the board and the two small side fins add hold through the turn and drive off the bottom. The 4-A holds when it is asked to and lets go when the rail comes off, which is what keeps a longer board from feeling locked in. Side bite size is the adjustment left to make: the 3.7" puts more bite in the tail, the 3.25" leaves the board closer to the single fin it was before the sides went in.
Who it suits
Longboards and mid-lengths with a centre box and two side plugs, across a wide spread of conditions. This is the set for a board that is too loose in the pocket on a single fin alone, but would lose its glide with a full performance 2+1 cluster in the rails.
If this is not the one
Boards plugged for FCS rather than Futures? The Greenough 4-A: 2+1 Combo - FCS Compatible is the same set on FCS bases.

Why Volan?
Volan is a woven fiberglass cloth laid by hand and finished with a resin that cures to a warm amber tint. It flexes differently than solid fiberglass — more spring, more life, more feel through turns. Where solid glass is stiff and direct, volan breathes with the wave.
The hand-laid process means each fin has subtle texture and character. It's heavier, which adds momentum through flat sections. Surfers who ride volan describe it as "warmer" — the fin does more of the work, trimming and holding without demanding constant input.
