Two plain reference tables that answer the two questions a slowing swing raises first: which shaft flex, and which ball. Both are free, sourced, and dated — no email, no sign-up.
Swing Speed & Shaft Flex Chart
Find the shaft flex that suits your driver swing speed — the first thing that changes as the swing slows down, and the cheapest to get right.

Ball Compression Chart
Match ball compression to your swing speed, so you stop paying for spin a slower swing can't unlock — and start getting your distance back.

These are starting points, not a substitute for a proper fitting. If you have a launch monitor or a fitter within reach, use them — measured numbers always beat a chart. But if you’re buying online and just want to be in the right ballpark, these tables get you there. See how we pick for the reasoning behind them.
