Since purchasing my 20 degree #3 hybrid over a year ago I put my #5 iron in retirement because I had so much trouble hitting it. I came across an iron drill video by David Leadbetter on Youtube that reminded me about keeping my hands on impact ahead of the ball. I think after re-evaluating my swing I was releasing on impact pre-maturely. I retrieved my #5 out of retirement and started practicing with it again using his tips. The results were amazing. The first video is with David and the iron drill entitled "Great Iron Play".
The second video is the result of my practicing with the #5 iron for a few days resulting in clean contact.
