why can't i find a driver i like?

i've had my nike sq dymo 2009 for about 2 years now.  i hit it well but put an unfortunate amount of high spin on the ball (4kish), even with my draw.  i hit it straight and long but really want a driver that can be the same but with less spin so that i can get some extra roll and distance.  i think i've tried every mainstream driver on the market with inconsistent results.

1. the 910 d3 i hit consistently, but at 240 yards (no roll) and 4k spin every time i swung.  i liked the consistency but i hit my current driver about 260 on average.

2. i tried the cleveland 270 because it is supposed to spin less, but i just flat out didn't hit it well at all

3. tried the i20/anser and they seemed to carry the same as my nike (tried on a range) but the spin was nearly impossible to read without a launch monitor.  i assume they spin lower simply because they are designed too.  i hit them both identically, might be the best of the bunch.

4. i tried the razr fit with the same results as the 910, and the adams speedline had about the same results too.

5. the only driver i tried that i liked but had inconclusive results with was the nike vr pro limited edition forged tour driver.  it felt great and i was hitting it the same distance as my current driver with spin closer to 3k.  i unfortunately didn't hit it enough nor did i have my current driver with me to compare to on that particular electronic range in-store.

any other suggestions out there?  maybe i don't need to be switching drivers at all, it's just that with all the new technology in clubs, i'm mentally convinced there is a better driver out there for me.

i usually just go straight for the stock stiff shaft on every club.

Launch angle, trajectory and spin rates are 90% shaft and 10% head.

How does one go about finding the correct shaft? I have a Cobra S2 which I like but it has the stock shaft. I've wondered from reading various threads on TST if a different shaft would be better.

^this.  i really don't understand how to go try out shafts at my local golfsmith.

There is likely a knowledgeable fitter in house at your Golfsmith.  Tell him your dilemma and let him find some demos drivers for you.  When I was looking for a Titleist driver several years ago, I tried several differently shafted demos to see which gave me the best numbers on their launch monitor. It's that easy.

Sure, you could spend a couple hundred dollars on an after-market shaft, and many here will suggest that you do just that.  But I would recommend you try the stock shafts first. At a 20 handicap, it's doubtful that an expensive after-market shaft will make that much difference.

As Harmonious has stated about Golfsmith. They fitted me for driver, 45 min later, I walked out of there with a used driver that matches my swing. YES the shaft is something that I never would have tried if not for the fitting. Secondly, Golfsmith has extra bays that you can hit used drivers in and simply experiment without paying for a fitting. Good Luck.

You need a good fitting session to find what's right for you.  That said you can go in there with an idea of what clubs you would prefer and then they can work around that with shaft options and adjustability.
