Looking at ordering an iron set at some point. Probably after the 22's release. But had some questions about building a custom set. Mizuno's site mentions that they offer lighter heads which can be used to make the SWs to a standard balance up to +1/2" longer. (It doesn't say anything about heavier heads for shorter builds though.) It also says on the site that irons can be built from 1" shorter to 1.5" longer. I'm trying to explore whether or not the build i have below would be able to be successfully built without alot of significant issues. (I'm mainly interested in the swing weights being able to be acheived. I know i can always add a bit of lead tape if needed, cause this build would tend to create lower swing weights than standard unless heavy heads were available). See below for the build in an MP-18. Would this be doable?
