One thing that taylormade has always done right was put a high quality shaft into their high quality drivers.
Yes they do. Anything from TaylorMade that is from the TP line will come with a great shaft. Granted, that's why the drivers are $600+, but you get what you pay for. The shaft is much more important than the head, so paying a little extra to get a good shaft is fine with me. And now a days, with more and more companies moving away from "OEM" shafts, and installing more "Upmarket" shafts, it only helps.
It wasn't long ago that basically Titleist was the only company that would sell a driver off the rack with a custom shaft. But, go in any shop or store these days, and practically all you see are the green NV, the yellow and black V2, the red OZIK, and so on. It's good to see. Even if those shafts aren't SUPER high quality, they are better than the crap we used to get stock.
I've had 3 TaylorMade TP drivers, and all have been fantastic. I had the original R510TP with a TP 757 Speeder. I had an original R7 TP with a TP Diamana Blue. And I have my current SuperQuad TP with the stock Re-Ax TP Rombax. I did hit my old Titleist 905S with a Fuji ZCom BW65 a tad straighter, but no where near as long. The SuperQuad is very straight, but that 905 was like a frozen rope. Didn't get much distance, but it was laser straight.
