I have only recently started using Hybrids and I have been surprised how difficult they were to hit. I've tried two different approaches. First is to set up and swing like a long iron. Second is to set up and swing like a fairway wood. I have found that the Fairway wood approach produces a much more consistent ball flight.
There are many articles I have seen saying to swing like an iron but that is just not what I am finding.
BTW my Hybrids are 4 and 5 R11 Rescues.
