5-9 iron with DG XP R 300 shafts. I am generally not a fan of the Dynamic Gold shafts, but those are the only shafts I have been able to hit at demos, and I was perfectly satisfied with the results. Cleveland does not offer the KBS Tour 90 shafts with the 588s, so the only other choice for me would have been PXi. If I decide I don't like the DGs, I might upgrade to KBS Tour 90s at some point. I also might be a 4 iron at some point, but only if I really love the 5 iron.
