Stiff Driver

Any suggestions for a new driver? Also does a stiff shaft driver go further than a regular?what about loft?

New driver, hmm. Well one thing... I'd advise against getting an Taylormade R-7. The extra bucks don't seem worth it when all you're doing is changing the location of some weights. If you're a bad slicer (or even only a moderate one) these weights won't help you at all. It's more a micro-adjustment to a slight draw or slight fade or something. To me, it seems much simpler to just turn my hands over a bit or close my club head or open it or whatever depending on how I'm swinging. This is something you can adjust on the fly whereas these weights stay in one place the entire round. Anyways, I have Ping G2 and love it, so I suppose the G5 would be a good choice. Really, there isn't much of a difference between these drivers. You could get Callaway, Ping, Cleveland, Nike, etc. and basically have the same product. I would choose the cheaper (or at least reasonably priced) of them. Look for a sale or something. Now the difference is in the shaft, and loft, as you say. For loft, depending on your skill level, the other answers are appropriate... ten and a half etc. I use a 9.5. I tried hitting the same club with a 10.5 and the ball seemed like it just went straight up. I don't know what it is about my swing but I need the lower loft. I've never tried 7.5 degrees though... Anyways. Shafts are all different. I'd recommend getting a regular flex unless you swing very hard (which you shouldn't). You could go ahead with a stiff shaft if you have a fast swingspeed (and a handicap to match it). Watch out for where the kickpoints are on the shaft though. Higher and lower could affect the ball flight as much as the loft (trajectory). Usually you would want to investigate alternate shafts for common stock clubs. They never have the best shafts right from the get go unless you just happen to match a swing profile that works for that shaft. As it is, I've got the factory shaft in my ping... Though Aldila 65 is also put in other clubs.
Distance: no stiff does not go further. Even for the better player stiff if anything makes the ball go not as far. The flex in a regular shaft provides extra distance. Players switch to stiff only if they have a fast swing speed and that flex leads to inaccuracy. Loft, I'm not sure about. In the past they thought 7.5 degrees was longer than 10. Now the drivers seem to be all carry and no roll. I'm not quite sure. My loft is in between anyways...
