Recoil 760/780

I see some Callaway iron sets as having Recoil 760/780 sets. I don't understand what this means. Do these sets have both 760 and 780 shafts installed? Or does it mean one type or the other. In particular, I have seen Callawy Rogue Pro sets listed like this. Can anyone explain waht this means? Thanks!

780 if F4 (Stiff)

The Recoil 760 and 780 are "brother" shafts. 760 offers A flex (68 grams) and R flex (70 grams), and 780 offers R (80 grams) and S (86 grams).

Here is the link for the 760/780 ES + Smacwrap (contains extra vibration damping):

Earlier non-Smacwrap Recoil 760 and 780 are a couple of grams lighter each.

Stock shaft for the Rogue Pro is the XP 105; the 760/780 is not a stock shaft, although it may be a low-cost or no-cost upgrade.

Thank you!

Not quite right. The number relates to shaft weight. 760 is a high 60’s gram shaft and 780 is a 80’s gram shaft. Both are offered in R and S flex. I’ve been testing the 780 S in a set of Srixon z785s for a few weeks. Really nice feeling but wish they offered one a bit heavier

It is actually exactly right. But you have to understand the context of the question is in terms of what Callaway offers, not what UST has available. The two are not the same.
