Shaft Stiffness and Ball Flight?

[Jon Hoover]

About a couple years ago i got a new driver the R11 for Christmas, it was 10.5 and regular flex, it worked much better then the 10 yr old driver i had been using but i still sliced the ball. Fast forward a year or so and i broke my collar bone in a motorcycle accident, but i was still hitting balls (with one hand) a day after the accident. While i was playing during my healing and as a result i started using more body/hip movement. Then about 3-4 weeks after I got new irons, it was my birthday. When i got the irons they measured my swing speed around 95 ish so i opted for the stiff shafts on the RBZ irons. So its been about 4 months and i love my Irons i will always draw or even double cross hook them, but I always either fade or slice my driver(3 wood same issue and shaft). What do you think about this? I have read many topics and most say that its your swing path and shaft stiffness makes a marginal difference could it just be that my driver swing is opposite from my irons, or is it the shaft or a combination of both? I know i should get a swing analysis and see a professional and all that expensive stuff but i just want to know what some peoples opinions are on this before buying some new shafts.
