Generally, the nature of the design on most modern “traditional” shaped hybrids, makes the playability very high. Lower, wider profiles tend to put the vertical and rearward cg locations in positions that make them more stable and easier to hit. Sizes vary, as they do with irons, but the horizontal length is generally similar to some higher playability irons, but longer than traditional shaped irons, which also makes hybrids more playable. So, in general, a well designed hybrid should have a high playability. That being said, if the structure internally and the wall thickness of the shell is designed poorly, it will not perform as well.
I would say that having a well designed hybrid in your bag is better for most players than long irons and in some cases mid irons. Anymore, with the stronger lofts on irons, 3-5 irons are definitely “long irons” and I might even put some 6 irons in that category. The player just has to be sure when they are deciding on the set make-up with irons and hybrids that they have all the distance progressions they need through the bag.
The reason we have not done hybrids in the same manner as irons is mainly due to the fact that the variation in hybrid playability is less. Also, simply time and availability. Maybe in the future, but for now I will continue to do the 30-40 new models of irons that come out every year.
