Orlimar's exclusive use of Alpha 300 stainless steel material in the VT830 fairway wood makes it one of the first fairway woods on the market to feature a COR (Coefficent of Restitution) of .830- the legal limit set forth by the USGA. A COR of .830 allows each golfer the opportunity to maximize distance from the tee - and now you can maximize distance from the fairway. Most of today's fairway woods have a COR between .770 and .800. With a COR of .830 you can expect to increase your distance up to 6%.
