Before entering span and pitch measurements into a spec sheet, you need to identify which **grip type** the bowler uses. The grip type determines how the fingers sit in the ball and directly affects which measurements are relevant. Most fitting sheets — whether handwritten, printed, or from a previous software system — record grip type either explicitly or implicitly through the measurements themselves.

## 🎳 The Three Standard Grip Types

Spectre Cloud supports the three IBPSIA-standard grip types. Understanding how each is defined helps you read any fitting sheet accurately.

<table id="bkmrk-grip-type-finger-ins"><thead><tr><th>Grip Type</th><th>Finger insertion depth</th><th>Typical bowler profile</th></tr></thead><tbody><tr><td>**Conventional**</td><td>Fingers inserted to the second knuckle (middle joint)</td><td>Beginners, recreational bowlers, seniors, youth</td></tr><tr><td>**Fingertip**</td><td>Fingers inserted to the first knuckle (tip joint only)</td><td>Most competitive and league bowlers; the most common adult grip</td></tr><tr><td>**Semi-Fingertip**</td><td>Fingers inserted between the first and second knuckle</td><td>Transitioning bowlers; less common</td></tr></tbody></table>

**Note:** The overwhelming majority of adult league and competitive bowlers use a **fingertip grip**. If a fitting sheet does not explicitly state a grip type, fingertip is the most likely default for an adult bowler — but always confirm with the bowler directly.

## 📋 How to Read Grip Type from a Fitting Sheet

### 🔍 When grip type is stated explicitly

Many printed and digital fitting sheets include a dedicated **Grip Type** or **Style** field. Look for labels such as:

- ✅ `Grip: Fingertip` / `FT` / `F/T`
- ✅ `Grip: Conventional` / `Conv` / `C`
- ✅ `Grip: Semi-Fingertip` / `Semi` / `S/F`

When you see any of these, select the matching grip type in Spectre Cloud before entering span measurements.

### 🔍 When grip type is implied by span measurement style

Older or simpler fitting sheets may not label the grip type, but you can often infer it from **how the span is recorded**:

- ✅ A sheet with a single **span measurement** (e.g., `Middle: 4⅛"`, `Ring: 3⅞"`) and no further qualifiers typically indicates a **conventional grip** — the span is measured to the second knuckle.
- ✅ A sheet with span measurements labeled as **Full Span** (`F`) or with a separate **Cut-to-Cut** (`C`) or **Oval** (`O`) notation indicates a **fingertip grip** — these are the three span sub-types used exclusively for fingertip drilling.
- ✅ A sheet with inserts noted (e.g., `finger inserts: yes` or a specific insert size listed) almost always indicates a **fingertip grip**, since inserts are standard practice for fingertip bowlers.
- ❌ Semi-fingertip is rarely recorded on older sheets — if the span measurements seem unusually long for fingertip but short for conventional, flag it and confirm with the bowler.

### 🔍 When grip type is implied by pitch notation

Pitch values can also hint at grip type. **Conventional grips** typically record fewer pitch measurements or use zero/reverse pitches throughout. **Fingertip grips** commonly include forward pitch on the fingers (e.g., `¼" forward` or `½" forward`) to accommodate the shallower insertion depth.

**Tip:** Pitch alone is not a reliable indicator — many conventional bowlers use forward pitch and many fingertip bowlers use zero pitch. Use pitch only as a supporting clue, not a primary identifier.

## 🛠️ Selecting Grip Type in Spectre Cloud

1. Open the spec sheet you are creating or editing.
2. Locate the **Grip Type** selector in the spec sheet header or measurement section.
3. Choose `Conventional`, `Fingertip`, or `Semi-Fingertip` based on your reading of the fitting sheet.
4. Spectre Cloud will adjust the available span fields and IBPSIA auto-suggestion logic to match the selected grip type.

**Important:** Selecting the wrong grip type will cause span fields to mismatch the bowler's actual measurements and may produce incorrect IBPSIA auto-suggestions. If you are unsure, choose **Fingertip** as the default for adults and verify with the bowler at their next visit. *Verify with Spectre team: confirm the exact UI label and location of the grip type selector within the spec sheet form.*

## ✨ Tips for Transferring Legacy Fitting Sheets

- ✅ When importing data from handwritten cards or Ebonite ProShop Coordinator records, review grip type field by field — legacy systems used inconsistent abbreviations.
- ✅ If a bowler is getting a new ball drilled at the same time you are entering their history, confirm their grip type in person rather than relying solely on the old sheet.
- ✅ For youth bowlers whose hands have grown since their last fitting, treat all old grip and span data as a starting reference only — re-measure before drilling.

**Tip:** Not sure which grip type a new walk-in bowler uses? Ask them to hold their hand flat and look at where their fingers naturally curl — fingertip bowlers typically have calluses or grooving at the first knuckle from years of fingertip use.
