I have used these irons (Cally Steelhead L85s) for the maybe 5 weeks or so, having upgraded from the L59 Pings too. On paper they have better specs in every regard, and I find this to be true in reality too.
A few things to consider - yes, higher, longer clubs will likely be effected by wind more. Ball spends more time in air = more impact from wind. Recognise also these clubs have more SPIN than the previous clubs, which means the amount of spin you put on the ball has a greater impact to trajectory, distance and what happens when it lands. I think this is one of the trickier things to tune in, but also gives you more "play" or "workability" in your shot with higher spin clubs.
Kudos to you if you have the patience and energy to map clubs by bashing balls up and down a flat fairway. I won't beat you, as I just play 'em and get used to them. I find all club changes take some time to adjust to, even if the new ones are "better".
Obviously the other major factor here is the ball you use, and of course the other environmentals like green speed, tees, wind, etc.
