Bearing in mind that with golf clubs and shafts its all subjective but here is my 2 pence worth.

Irons

I would rate the clubs in the following order:

1) Mizuno MP60
2) Bridgestone J33 CB
3) Taylor Made TP

I have hit both the MP60s and the J33CBs before and the difference between the two is very very small and it will come down to personal tastes and feel.
I liked the look of both sets of irons and they have the look that I am looking for which is a blade like look with a thin topline and a narrowish sole profile. Anything that looks gimmicky or plasticy then its out.
As for feel the Mizuno's are buttery soft and you can't be a pured shot out of the middle with them. The Bridgestone's whilst they a bit 'clickier' than the Mizuno's they are still very soft. Again it comes down to personnel preference. Given the choice I would be happy to play either. If you are worried about quality I would rate the Bridgestone's slightly higher than the Mizuno's. The Mizuno specs and tolerances can be out a little (as can all clubs) but the Bridgestone's that I have (J33 Combos) came out bang on spec.
I have not hit the Taylor Mades but I have seen them a few times and they are not that bad looking but they do look a bit too busy for me and also after help reshaft a few TM drivers and irons, I am not that enamored with their build quality. I have read reports that the irons do feel harsh and that they are not a soft as say the Mizuno or the Bridgestone.

Shafts

I have been playing PXs for the past year or so. I feel that they are butt stiff shafts and even thought they play stiffer than say your Dynamic Golds they are not harsh but feel very smooth and pretty progressive.
The ball flight that I get from them is pretty flat, the ball starts off with a high launch and then plateaus at the top of its flight whilst still going forwards. Its a good shaft if you want to keep the ball down a bit better whilst still having a high launch.
But in saying that I am going back to Dynamic Golds for a while. Not as smooth as the PXs but they are heavier as I found that I liked the weight and feel better in the DGs. Sometimes with the PXs I felt that I could not feel where the club was and that I could not get that sensation that I was looking for on good hits and on mishits.

Hope this helps.
