Isometric 150 Long: the lowest-rated Isometric on Yonex’s 1996 catalog spread
The last column of the spread
The Isometric 150 Long is the sixth and last racquet on the Isometric spread of Yonex’s 1996 Asian catalog, under the heading “Long” beside the 250 Long. Like it, the 150 Long carries a New tag, the line “High speed touch player,” the Built-In T-Joint and the player level Advanced. The scan is undated; 1996 is the scan host’s year for the catalog, and the New tag is evidence of a recent launch, not proof.
Plain graphite, 3 across the board
The catalog prints a graphite frame and a plain graphite shaft, not high modulus, and rates it 3 for flex, power and control, the lowest ratings in the Isometric spread. No Yonex document names a flex word, weight class, balance point, length, made-in country or item code for it, so those fields stay “Not documented.”
No named player
Yonex names no player for the 150 Long, and the spread has no player photographs. “Advanced” is a player level, not a user.
Next to the 250 Long and Power 200
The 250 Long beside it has the high-modulus shaft and a 4 for flex, power and control; the Power 200 has the high-modulus shaft, flex 3 and a 4 for power and control. In the photo the 150 Long has a blue and green frame and a navy soft cover. Yonex names no color, and no edition is documented. Yonex Japan’s own Isometric pages, which carry per-model pages from 2000, are a separate record with their own item codes.
One catalog and nothing after
The 1996 catalog is the only Yonex document that names the 150 Long. Its sibling 250 Long reappears on Yonex’s 1999 spec chart and on Yonex USA’s 1999 Isometric page; the 150 Long does not, and the 2000 Asian catalog’s Isometric pages omit it. No Yonex catalog or list from 1997 or 1998 is documented, so 1996 is its last documented year rather than a production end. No Yonex document found prints a price for it. No verified sales are recorded yet.
Checking the name
No counterfeit of the Isometric 150 Long is documented. With no Yonex item code, the printed model name is the identity check, and it is easily confused with the 250 Long beside it and with Yonex Japan’s Isometric 250. On a frame about 30 years old, the throat, hoop and grommets deserve a close look.
A one-catalog model
The 150 Long is the thinnest record among the 1996 Isometrics: a name, a tag, three ratings and a photograph. It marks the bottom of the Isometric spread in that year’s catalog, below the 250 Long and the Power 200.
Yonex documents the 150 Long only in its 1996 catalog: graphite frame, graphite shaft (not high modulus), Advanced level. No item code, weight class, flex word or country of manufacture is documented. The model name is the check: look for “150 Long” in the frame or cover print, and do not accept “250 Long”, “Power 200” or a bare “Isometric” as a match. Colors are read from the catalog photo only (blue and green frame, navy cover). Inspect the throat, the hoop and the grommets for cracks on a frame this old.
The 150 Long suits a collector filling out the 1996 Isometric spread. With a single Yonex source, any detail beyond name, shaft material and ratings, such as weight, length or made-in country, is a seller’s claim until a Yonex record turns up. Confirm the exact name on the frame and ask for photographs of the throat and shaft.
