Inspired by the set composition of Jordan Spieth I am thinking of dropping the Iron-3 out of the bag when purchasing a new set of 716 CB. However by doing so I believe some loft adjustments is necessary not leaving a a huge gap between my 915Hd and lowest iron/ Iron-4. 

Would appreciate some thoughts what would be the best solution, either play a 1degree weaklofted Iron-3 and skip the Iron-4. Or strong loft an Iron-4 2 degrees like in attached picture? My major concern is wether playing an Iron-4 with 0 degree bounce will cause any issues. 

I am currently a 3hcp player, likely (hopefully) on my way down.

Details in attached picture.

 

Thank you in advance!
