Have been playing the mp15 4-pw for the last 3 years and have enjoyed hitting them. I play off 9 and was looking to upgrading my irons to the jpx 919 hot metal pro 4-6 for a little more forgiveness/distance, and jpx 919 tour 7-Pw Ot not sure if I should stick with the mp 18 line - 4-pw mmc irons. Any thoughts?
