So I tried a 7 wood, albeit in a non-ideal shaft, but it inspired this idea.
Build a club that would be both a 4 wood to 4 utility iron rapper and 13.5 mini driver to 4 utility iron replacement.
Thinking getting a tsi2 5 wood, cutting it down to 41" (and adding weight to get SW back to normal), and then depending on when I use it, play it at 17.25 when it gaps the mini driver setup, and then jacking up the loft to 19.5 when it gaps the 4 wood. Or get the TSi3 5 wood so I can put the weight in fade when adding loft, and moving to draw when dropping the loft.
It makes sense on paper, but probably will be a complete failure. Stay tuned.
