I just started playing and for some reason, I can hit irons and woods, but hybrids are so hit and miss. Like my body doesn't know what it wants to do. I try to hit it like an iron, doesn't work. I have better success hitting it like a wood (M2 19 degree).
Lots of good points in this thread. Mostly comes down to personal preference and what your swing is like. My personal preference is I would never choose a 7 wood over a 4 hybrid but that's simply because i like hitting hybrids. I grew up hitting hybrids not woods so I've grown used to them. I didn't even carry a 3 wood until a few years ago. In that gap you are looking to fill seems like a 7W would work for you. Maybe even a shorted 7W would fill the gap nicely and be easier to hit.
I won't rule it out forever. Looking for a hybrid that is more iron like, and I'll stick an iron shaft in it and see.
