I just ordered the 01...anxious to try it out. I went with 34" and a 72* lie angle which is my standard. After just reading a couple books by Stan Utley and Dave Stockton I had the loft increased to 4*. Utley seems to like 5* of loft but flatter lie angles. Stockton mentioned 4* to 5* loft but that is based on his forward press style.
