Having a discussion about some irons - MP18SC ordered standard lie but +1/2" Project x 6.0...turned up D3 really nice but will be probably in need of making them more upright....ordered the matching MP18 5 Fli-Hi and having issues with my order...came in at D6-7...part of the explanation maybe that as this was ordered +1 degree upright that affects swing weight!?...more than likely a standard head weight was used but interested to know what changing lie does for an iron?
