Hi Nobs.
I am the same...tried so many 3 woods....Troublesome to say the least. I have been using the 358 more recently, but trying to settle on what shaft is best for this head. Interesting the Ahina is working out for you....Light weight in a stiffer profile, I may have to give that a run. Great article by the way, easy to take something out of what you write when you cover all bases.....
