# Ratio of Angles ## ? The “Ratio of Angles” The **ratio** between the *drilling angle* and the *VAL angle* gives insight into **how sharp or smooth** the ball’s motion will be. **Ratio = Drilling Angle : VAL Angle** ### ? **Higher Ratio (e.g., 70° : 30°)** - More length in the front part of the lane - Sharper backend reaction - Best for high-rev players or when lanes are dry ### ? **Lower Ratio (e.g., 40° : 70°)** - Earlier, smoother roll - More control on heavier oil or sport conditions - Best for speed-dominant or lower-rev players --- ## ? Example Layouts

Bowler Type	Example Layout	Ratio	Reaction Shape
Speed-Dominant	40° × 4" × 70°	1:1.75	Earlier, smoother reaction
Balanced (Tweener)	55° × 4½" × 40°	1.4:1	Benchmark shape
Rev-Dominant	70° × 5" × 30°	2.3:1	Length with sharp backend

--- ## ? Summary

Term	Controls	Lower Value	Higher Value
Drilling Angle	Skid phase	Earlier roll	Later roll
VAL Angle	Backend motion	Sharper	Smoother
Ratio of Angles	Overall shape	Smooth/control	Angular/strong

--- ### ? In Short: > The **ratio of angles** defines how fast or slow your ball transitions from skid → hook → roll. > > - **Higher ratio** = more angular shape > - **Lower ratio** = smoother, more controlled shape > > [![POWERPNT_Yrcxq1AQrz.png](https://wiki.spectrebowling.com/uploads/images/gallery/2025-10/scaled-1680-/powerpnt-yrcxq1aqrz.png)](https://wiki.spectrebowling.com/uploads/images/gallery/2025-10/powerpnt-yrcxq1aqrz.png)
