I was able to hit the new P790 iron for a bit tonight so I can give a small review.
I am not a fan of the satin look. The satin sole reminds me of the speedblade. I am not sure why but the head does look bigger than the previous versions. On to the performance.
The feel is the same as the previous models. The ball speed and launch are definitely higher. The ball speed is what really shocked me. These things go really far. Maybe too far. I even bent the club a few degrees weak and it was still giving me high ball speeds.
