Sub 70 799 アイアン

The 699 is a players distance iron with a thinner topline, less offset, and a smaller head. It rewards a reasonably consistent strike. The 799 is a full step further into forgiveness with a wider sole, more offset, and a lower center of gravity. If your misses are scattered across the face rather than clustered near the center, the 799 is the right side of that line.

Sub 70 sells direct and handles this with a trial and return policy rather than a shop demo bin. You order a set built to your specs, hit them, and send them back within the trial window if they are not right. Check the current terms on their site before ordering, since the length of that window and what counts as a return has changed over the years.

Super game improvement irons generally run stronger lofts than a traditional set, and you should assume the 799 follows that pattern. The practical effect is that your pitching wedge will not fit neatly under the gap wedge you already own. Sort your wedge lofts at the same time you order the irons rather than after, and get the bottom of the bag mapped out in one go.

Match the shaft to your speed, not to what your friends play. Most golfers buying a super game improvement iron are better served by a lighter graphite or a soft-stepped steel than by the stiff steel that comes standard in a lot of stock sets. Sub 70 lets you pick from a wide list at order time, so use that. If you have any recent launch monitor data, send it along with your order and let their fitting team weigh in.

Both, and it matters which one is doing the work for you. Stronger lofts add yards on center strikes. The low center of gravity and the face design add yards on the strikes you actually make, which is the more useful gain. If you are coming from a ten year old set, expect a meaningful jump. If you are coming from a current game improvement iron, expect a smaller one and more benefit in launch height and consistency than in raw number.
