I picked up this combo after finding it on EBay and then being reminded of it by Dave's post about the deal. After some thought I decided to go ahead and went for the 10.5 head and the SK Fiber Pure Energy Red shaft. The seller was really good and kept me informed of the progress of it once shipped and I'd recommend him to anyone. Link below.

This is more of an "initial thoughts" post than a review but I will add more once I've had some more time with my new found friend.
First up it looks great, I mean really great. Sets up beautifully behind the ball and the head is awesome. I had it fitted to my TLT chart although it's close to standard anyway.
I hit 50-60 balls on the range and it produced a good ball flight - not too low but no ballooning and very penetrating. The shaft feels very stable and the dead centre hits feel really, really good. It's long too. A very serious club for not that a serious amount of money. If you are looking for a new driver I'd certainly give this a try, it's every bit as good as any OEM driver I've hit but much less of a hit on the pocket.
