MPF is a great way to compare heads on paper, for those that like the system. Works really well in the Maltby line up. Mixed results when you look at other brands. I am a fan of the MPF design philosophy.
1. Ping's fitting cart is going to jam you up a little on the shaft options, the two CB options are mid launch and the blueprint uses the lower launch black vice the blue you play now. If you love Ping ( I do, and my best player has been a lifelong Ping gal) best to fly to Scottsdale and do the factory fitting. Fit with the Ping engineers on one day, and validate it 2nd Swing. See Ping website"fitting experience". Depending on where you live, you may be able to do this without a hotel stay.
2. Call / email Golfworks with your current Ping specs and launch monitor numbers, and tell them what you would like to get to and they will have a few suggestions. Order one or two test clubs, and have fun with the experiment.
my bet: TS4's w/ Kuro Kage R+ or S will be you GW's recommended club.
