The stock set was 3-PW with a 34-degree 7-iron and a 46-degree pitching wedge. Specs below are the men's standard steel-shaft build.

Finding a used set
The Mizuno MP-18 MB is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
