Spine guidance

Velocity estimates

Using the standard ATA / IBO velocity formula, a 440gr arrow at the Darton TriTech 35's 335 fps IBO should chrono around 241 fps off your bow. Real-world velocity will vary by ±5 fps depending on string condition, peep + d-loop weight, and tune state.

Common tune issues on the Darton TriTech 35

Over-spined arrow. The biggest issue with the Darton TriTech 35 is shooters going to 300 spine when 340 is correct, then seeing tail-high tears that take forever to chase. Start with manufacturer spine chart, validate with the builder.

Wrong sight radius. If you're using a slider sight, the sight radius from peep to pin housing affects every yard mark on the tape. The Sparrow sight tape generator (Pro) needs this accurate to the 1/8".
