Thanks for the nice comments. We have really excited about this set and are happy it is finally in stock. The intent was to offer it as a true hybrid set, to be matched with the STi-H hybrid 3,4,5, but I completely understand that a 4 and or 5 IRON might be more appealing to some. If the sales do what we believe they will, it might make sense for us to add at least the 5 iron. The trend over the last few years, for all types of heads, is that 5-PW, GW is now more the standard set. When we develop a set, there is a minimum number of pieces we need to reach with each number. The minimums far exceed the projected sales, with the trends the way they are, on 3 irons and 4 irons especially. We just felt that since this set targets those players that need at least Super Game Improvement features, the 3 and 4 did not make sense, and since were making the hybrids 3,4,5, starting the set at the 6 iron would encourage matching the hybrids with the irons. We just do not sell many 3 irons at all, and the 4 irons are slowing significantly, across the board. That being said, adding at least the 5 iron could be in the cards. We will consider as the season moves forward and we can see how the sales progress. You could add the STi #5 iron to the set. It is Ultra Game Improvement and would be a good addition for the player that prefers the iron look but needs that extra level of stability and forgiveness an Ultra Game Improvement iron provides.
