What the differences mean
At the 7-iron, the Idea a2 OS is 33° and the Idea a7 OS is 32°, a 1° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the Idea a7 OS should carry roughly 3 to 4 yards further with that club, on a slightly lower, shallower flight than the Idea a2 OS. Across the 8 clubs both sets share, the Idea a7 OS averages 0.4° stronger, with the largest gap at the 6-iron (29° vs 28°). Beyond loft, the Idea a2 OS 7-iron sits 0.2° flatter (62° vs 62.25°), which nudges start direction slightly right for a right-hander.
The sets are built differently: the Idea a2 OS runs 5-iron to LW (9 clubs), the Idea a7 OS 6-iron to LW (8 clubs).
Both are super game improvement irons, built for high handicaps, beginners and slower swing speeds. The most forgiving category — very wide soles, maximum perimeter weighting and the strongest lofts. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
Both heads are listed as investment cast. The Idea a7 OS's hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the Idea a2 OS, at some cost in feel.
There are 4 years between these sets (2005 and 2009), more than one design generation. Over that time irons moved toward stronger lofts, thinner and faster faces, hollow and multi-material heads and wider use of tungsten, so the newer set is not simply a better version of the older one: it may launch and spin quite differently. Here the 7-iron loft moved from 33° to 32°.
Which should you choose?
The Idea a7 OS is the stronger-lofted set — up to 1° stronger than the Idea a2 OS on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
