After now playing a few rounds with these new clubs I can definitely say they are the business. The longer irons without doubt land softer on the greens than the i15s and their accuracy even when the ding is missed is excellent.
An added bonus is that with the meter speed being slower than the i15s, can't say I noticed tbh, I am now dinging a higher percentage of my lob wedges, instead of the usual hitting them early more often than not.
The new driver, wedges and irons are as close in meter speed harmony as I can remember in my 18 months here using all club combinations. Something that numerous players called out for in the past :^)
