A large head, a wide sole and a low deep centre of gravity make this one of the easiest sets to launch that Callaway has produced. The 360 Face Cup wraps the face around into the body so the whole thing flexes at impact, which keeps ball speed respectable even when the strike is well away from the middle.\u003c\/p\u003e\n\u003cp style=\"margin: 0 0 24px 0;\"\u003eWith a 4 iron through pitching wedge makeup on regular flex steel, this is aimed at the golfer who wants maximum help and does not care what the club looks like as long as the ball goes high and straight. If you struggle to get long irons airborne, the OS is one of the best places to start. Plenty of standing distance and forgiveness for the money.\u003c\/p\u003e\n\u003ch3 style=\"margin: 0 0 12px 0;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"margin: 0 0 18px 0; padding-left: 22px;\"\u003e\n\u003cli style=\"margin-bottom: 10px;\"\u003e360 Face Cup technology for ball speed across the whole face\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px;\"\u003eOversize head with an internal standing wave for high launch\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px;\"\u003eWide sole and low, deep centre of gravity\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px;\"\u003e4 iron to pitching wedge, regular flex steel\u003c\/li\u003e\n\u003cli style=\"margin-bottom: 10px;\"\u003eBuilt for maximum forgiveness and easy height\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Callaway","offers":[{"title":"Regular","offer_id":58450535973212,"sku":"210000054081","price":299.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/8147\/2860\/files\/bigberthaspeedstep80540815-1366.jpg?v=1785331149","url":"https:\/\/tonyvalentine.com\/products\/callaway-big-bertha-os-irons-4-pw-regular-flex-steel-used","provider":"Tony Valentine","version":"1.0","type":"link"}
