sukkeun I haven't tried the new TE+ but it looks great. The TS3 and TS1-IM I have built demos of and they are both awesome. KE4Max is also a great head.
I played the original chrome version of the DBM and it was very nice. Forgiving for it's size. The one negative for me was the fairly sharp leading edge and I hear they addressed that with the new version. I was trying to decide between TS3 and TS1-IM, but now I feel I need to try the new TE+ as well.
I've always liked Wilson irons; it's been their one bright spot IMO although I hear the new wedges and woods are catching up. The D9 gets great reviews but seems to be a different head than the DBM or TE+. Maybe more inbetween TS3 and KE4Max? I haven't tried it so hard to say, but to me if you're either lusting after forged black irons or your not?
Most OEM irons are going to hold their value better than Maltby. I do think that's changing a bit with the new stuff though. They have a following on GolfWRX and someone there would probably pay a fair price for those irons. Also I don't think Wilson D9's will hold their value as well as say Titleist or Ping. In this case value may be a wash so get what you prefer.
The TT Score is a nice solid shaft. One of those steel shafts that's mid weight and fits a fair # of players kind of like the old Dynalite Gold. I think the TT Score may have come from Dynalite or Memphis 10 or such, but not sure. It's not graphite though so if you want light graphite that's where you should look. I would think GW has a Pak with their Pro Series (stiffer than you would expect) or KuroKage.
