I will assume you realize the 3-iron in that 2014 TP CB set is 18* of loft.
I therefore recommend you opt for the 18* Taylormade UDI #2 instead. It is also 18* but easier to hit. The stock C-Taper Lite 110 shaft also launches higher for more distance than the KBS 120 stock shaft in the TP CB-3-iron. The UDI's can be found brand new on ebay right now, and last time I checked there were a;sp some on Amazon as well. (Note: The reason I didn't recommend the #3 UDI is because it has 20* of loft which is much too close to the TP CB 4-iron loft of 21*).
If you decide you still must have a 2014 TP CB 3-iron, your best bet is Ironfinder.com or ebay, but having played both. I recommend the #2 UDI 18* option.
