Used Callaway Diablo Driving Irons

2010–2011

Callaway used the Diablo name on a 2009 Big Bertha, then spun it out on its own for two seasons. Diablo Edge (2010) covered the whole bag — driver, fairways, hybrids, irons and wedges — and replaced the 2008-09 Big Bertha irons. Diablo Octane followed in 2011 with a Forged Composite crown, alongside the Diablo Forged irons. Common and cheap second hand, and a lot of club for the money.
