I came from wood too, though not for 50 years, and that warm feel was the thing I was worried about losing when I tried carbon. Of your three, the Jacoby is the one that felt closest to wood to me — the V4 I hit with had a softer, fuller hit than the Cynergy, which felt a bit firmer and crisper in my hands. I have not hit the SMO, so I can't compare that one fairly. One thing I would add: the tip will change the feel as much as the shaft will. I moved from a super soft to a medium when I switched, and that took a lot of the hollow feeling away for me. If you can, try the Jacoby and the Cynergy back to back on your Schon before you buy — that is what made the choice clear for me, and at around 12.4 the Jacoby felt right.
