The long game

The decision system for your golf bag.

The place golfers visit before they adjust, compare, replace, or buy a piece of equipment.

The idea

Think PCPartPicker—built for the golfer’s bag.

Useful golf equipment data is scattered across charts, fitting manuals, product pages, and marketing copy.

BagSpec turns that evidence into clear decisions while preserving uncertainty. Driver adapters are first because a setting change is small, testable, and immediately useful.

Commercial rule

Revenue can support the work. It cannot rewrite the answer.

Clearly labeled retailer links can fund research when a qualifying purchase earns a commission.

The optimizer does not rank brands or settings according to commercial relationships. Read the affiliate disclosure →
