re: Week 26 of 52 2014 Golf Thread

Change of topic to call on the golf board gurus. Ive been playing golf for about three years. I've had the Callaway Razr x NG irons for about a year with the stock uniflex shafts. My swing has gotten more efficient and my swing speed has increased to about 100 mph on my driver. The past couple of months I've been hooking or pulling my irons a lot and just figured it was a swing flaw, which it partly may be. However, this weekend I hit some Mizunos that were equipped with DG S300 and I was hitting them a lot straighter and higher than my Callaways.

My question is: does anyone know exactly what the unifiex shaft flex is rated or can be compared to these days? In doing some research, there is a lot of conflicting info and it seems that Callaway may change the flex rating In the uniflex from year to year. I'm wondering if I should upgrade the shafts in my current irons or not. Thanks in advance!
