The new Z585 irons are forged from a soft 1020 carbon steel that offers you better feel and less vibration on impact. Srixon have also introduced a new Speed Groove, which is an internal channel on the laser milled SUP10 face insert, that is designed to give the club more face flexing at impact, helping to achieve enhanced ball speeds which in turn gives you extra distance and spin control going into the green.
There is a wider Tour VT Sole that has more trailing edge bounce helping with turf interaction, so the club is less likely to get snagged up which in turn provides you with a more consistent ball strike at impact.
I really enjoyed the feel of the ball coming off the face at impact and the softer carbon steel certainly gives you a great sound while the internal speed groove gives you plenty of ball speed off the face. I was most impressed with the forgiveness with the larger face giving you a bigger sweet spot, while at the same time still looking quite compact when placed behind the ball at the address position.
The Z585 can work with the new Z785 irons so you can combine the sets to use the cavity backed irons in your longer irons and the more blade like design for the shorter irons, I haven’t tested the Z785s yet, but what I can say is that I was very impressed by the Z585, the feel, the forgiveness and that larger sweet spot. I had a wonderful four days testing them over several courses and I would certainly recommend them if you are in the market for a new cavity backed iron.
