Eguller I do not know what they were, they were just a 'stock' set. But they did feel like feathers. Could not swing them at all. I had the A flex shafts that are under 60g, which I did not realize at the time of purchase.
Like you did, when I order irons, I always get them +1/2" or +1". This is after figuring out how they are getting around building these very low lofted clubs now. I thought the weights must be really low, and I've discovered that to be true. A 6i head is almost the weight of an older 4i, thus the reason they are now adding just a bit of length, to what used to be 'standard'. 6i now is around 37.888, when it used to be 37.5 or shorter. So, when I want a set of 6-PW, I know to order 7-GW, plus 1/2". If they feel light, I will not hesitate to yank them apart and add weights in.
That may not make sense to most, but it has worked well for me this year. It did actually confuse the fellas on the FB golf sites. But, they don't know things like FGI/GB members do.
