The Ping golf company was said to revolutionize golf with their introduction of the Eye2 irons. These irons featured perimeter weighting and healthy offset. These were almost universally regarded as the easiest irons to hit for many years to come. It the decades since, the perimeter weighting feature has been widely adopted while the healthy offset feature has been less so. What are the benefits or disadvantages associated with offset?
"Offset helps close the face quicker and can lead to hooks." FICTION.
If this is ever true it is due to psychology at setup. If one properly sets up with the clubface behind the ball and facing the target the face will close in the same amount of time, i.e. at the same point in the swing, regardless of offset. It's not like an iron byron machine will start hooking the ball if one attaches an offset club.
"Offset irons get the ball up quicker." FICTION
The offset puts the hands (further) ahead of the ball at impact. This will help someone with an early release reduce flipping and keep the launch down in addition to producing cleaner strikes. If anything, the offset feature counters the effect of high launch produced by the wide, heavy sole normally seen in the same category of irons.
"Offset irons have a higher moment of inertia." FACT
Simply put, the center of mass is further away from the axis of rotation (the shaft). This is the same reason driver heads have gotten so large from front to back. The offset irons have a greater resistance to twisting on off-center strikes.
"It is harder to work the ball with offset irons." NOT FACT
This all depends on what you mean by "work the ball". A golfer who is well-practiced with their clubs can produce a slice or hook with pretty much anything out of any clean lie. Flighting the ball in terms of high-low trajectory is another story and can be compromised with game-improvement clubs. I will get into the reasons for this probably in another thread.
Maybe you have dismissed offset irons for fear of the hooks or a high ball flight. I believe this is simply a prejudice caused by myth. If your ballstriking could stand improvement in general, I would recommend giving a heavily offset mid-iron a try-out on the driving range. Start with the ball teed up to remove ground interation from the equation and see if it helps you strike the ball cleaner or flight it better.
