I started golf about 2 years ago but i only get to play about 2-3 times a month. When i first started my dad gave me his driver. I know now in retrospect it was a bad thing to start off with. But its a original Nike SUMO 2 (460 or w/e its called) Stiff shaft with a 9* loft angle. I would say about 75% of the time i slice the ball about 30-40 yards either in the rough or way off the fairway. About 5-6 holes in a 18 round ill hit it dead straight about 215 yards or so. I shot a 93 this weekend on a par 72 with only a few fairway drives. Ive gone to the range and practiced many times but still the same outcome when i play. I can hit my 3 hybrid (20* regular shaft) about 190 yards perfectly straight about 90-95% of the time. I hit everything in my bag irons, hybrids etc. deadly straight with no slice. I was talking with a friend and he said i should get the new nike 5900 SUMO 2 with a regular shaft and either a 10.5* loft or a 12*. He said he thinks my swing is great but that my shaft is to stiff for me and my loft angle is too low. He is a golf instructor at a course and has about a 5 handicap so i think he is a pretty reputable source. What do you guys think? My swing speed is always around 90-100.
