I'm looking to put together a new set of irons. I am thinking about trying out a graphite shaft to see what they are like in irons. I hit an average ball, i.e., 150-160 yard 7 iron, average/slightly high trajectory, straight with maybe a hint of draw. Swing tempo is average, maybe slightly quick. I seem to prefer regular flex steel shafts over stiff. I am leaning towards a 431 cast iron such as GolfWork's CER 701+ 3C. I am going to put a 5 iron together for a test drive before putting the whole set together. My static fit dimensions are dead average and I typically fit fine to clubs off the shelf.

I have done a bit of research and here are some shafts I have come up with that would seem to suit me:
- Grafalloy ProLite Iron or ProLogic
- UST ProForce Rv2 75 Iron
- Aldila Tour Gold 85 Iron
- Royal Precision Graphite Iron
- GolfWorks CER (Nickel Butt or FW70)

I would like to keep lengths similar to steel shafted clubs with the swing weight in the D1-D2 range.

Any insight/suggestions/additions to this list? Any feedback from people who know what they are doing in club building would be appreciated.
