I had a chance to hit the 460 and 430 on the launch monitor today.
The shaft was an Aldila Rogue in stiff (not a perfect shaft for me, but to limit the variables I decided to stick with it during the session).
Looks:
Not my cup of tea at all. The carbon part looks quite nice. The white parts are distracting. Even if you don't see it at address, the bottom side does look very busy.
Feel / Sound:
Ok for a composite head. Not too loud and medium soft. Very difficult to judge where you have hit the ball on the face. Might have been due to the shaft. To me there was a little difference between the two heads. Especially with the 460 I was not feeling it - very vague. The 430 was a little better, but still not what I would expect from a high end club.
Performance:
Good ball speed, but relatively high spin no matter what settings I have been trying. The 460 was 1000rpm worse, the best ones of the 430 700 rpm higher than my current gamer. Carry distance of the 430 has been shorter than with my gamer.
All in all:
the results could be very depending on the shaft. Distance on good hits is ok, but not great (how should it be different within the given restrictions for drivers). Even if the performance of the 430 would be on the same level than my gamer (which might be possible with a different shaft and dialling the whole thing in) the looks would be a show stopper too me.
