FWIW, I think having the shaft perfectly matched to your swing tempo matters more than the head shape.
I play Hogan Apex blades that came with stiff Apex 4 steel shafts. My previous set was Hogan CFTs with graphite shafts. I was terrible with both of them. Big hooks at odd times. After having a launch monitor session and shaft fitting on the Apexes, I am merely bad.
Sold the CFTs, and I'm having a blast with the reshafted (now Rifle 5.0)Apexes. They now go long and straight.
My recommendation is to find a really goodclubfitter with a Vector launch monitor, video, etc.; find the best shaft type & flex (frequency matched) for you, then decide on the head. Most good clubfitters have a selection of heads that can be attached to whatever shaft with Conex fittings. I went though 8 shafts and 5 heads during the fitting session before finding the perfect one for me. The heads were the Apexes I was already using, but the shaft is totally different.
When my timing is right, I can feel the shaft load at the top and release exactly at impact.
