For most of 2007 I've been playing the following clubs:

Driver: Taylormade r7 425, 10.5 deg. stiff, graphite. Fairway: Taylomade r7 3 wood ST, stiff, graphite. Sonartec 2.5, 7 wood, stiff, graphite.  Hybrid: Taylormade Rescue Dual, 4i, stiff, graphite.  Irons: Taylormade rac LT, 3-PW, Rifle 6.0.  Wedges: Taylormade rac Black 54 & 60deg. Putter: Odyssey 2-ball, Center shaft.

In 2008 I will be playing:

Driver: Callaway FT-3 Tour, 9deg., stiff, graphite.  Fairway: Callaway BB 3 & 7 wood, firm, graphite.  Hybrid: Ping G10, 24deg., stiff, graphite.  Irons: Mizuno MP-32, 4-PW, Rifle Project X 6.0.  Wedges:Mizuno MP-Raw Black, 54deg. Mizuno MP-T Black, 60deg.  Putter: SeeMore FGP Bronze.

I love the response and feel of the Callaway HX Tour ball but will experiment with other balls.  I have tried the Maxfli Tour Fire, Precept IQ 180, Taylormade TP Red, and the Nike One Platinum.
