# 68" bow | Arrow Specs — 30lb Recurve Bow at 27–28" Draw

## Arrow Spec — 500 Spine (Preferred)

> Correct spine for a 30lb recurve at ~28" draw. The Sanlida Noble already includes 6 carbon arrows at 500 spine — these are the right choice for this bow.

## Arrow Spec — 600 Spine (Acceptable Alternative)

> Slightly more flexible than 500 — still works fine at 30lb, widely available, and often cheaper. Good backup option if 500 spine is unavailable at the right length.

<table id="bkmrk-spec-value-notes-spi-1"><thead><tr><th>Spec</th><th>Value</th><th>Notes</th></tr></thead><tbody><tr><td>Spine</td><td>**600**</td><td>Toward the flexible end for 30lb — acceptable, not preferred</td></tr><tr><td>Arrow overall length</td><td>**28–30"**</td><td>Same length requirement</td></tr><tr><td>Shaft material</td><td>**Carbon fiber or aluminum**</td><td>Both fine at this weight</td></tr><tr><td>Point weight</td><td>**100gr**</td><td> </td></tr><tr><td>Total arrow weight</td><td>**210gr minimum**</td><td>Same GPP floor applies</td></tr><tr><td>Straightness</td><td>**.006" or better**</td><td> </td></tr><tr><td>Max safe draw weight rating</td><td>Must cover 30lb</td><td> </td></tr></tbody></table>

## GPP Reference Table

> GPP = Grains Per Pound of effective draw weight. Based on 30lb effective draw.

## Do NOT Buy

<table id="bkmrk-what-why-400-spine-o"><thead><tr><th>What</th><th>Why</th></tr></thead><tbody><tr><td>400 spine or stiffer</td><td>Too stiff for 30lb — arrow will not flex correctly through paradox, poor flight</td></tr><tr><td>700 spine or higher</td><td>Too weak/flexible for even 30lb — inconsistent flight</td></tr><tr><td>Arrows shorter than 28"</td><td>Too short for her ~27–28" draw — safety risk</td></tr><tr><td>Fiberglass shafts over 30"</td><td>Heavy, inconsistent, poor spine rating — the included Noble arrows are better</td></tr><tr><td>Arrows rated below 30lb</td><td>Outside safe range — almost never an issue at this draw weight</td></tr></tbody></table>
