So i decided to pick up the game of golf, recently a lot of friends are starting up to and they've been bugging me for a while now i caught golf fever . The clubs im looking to buy are the callaway diablo edge's iron set, steel shafts with stiff flex. couple questions, im 23 yrs old, and about 5'6. it says these clubs are the longest irons ever, and on the callaway site you can customize them to be shorter . would these clubs be too long for me? should i shorten them? and when picking my shaft, what would you choose, true temper black gold or dynamic gold??? THANK YOU!!!!!!!!!!!!!!!!!!!
