Hi Dennis, 

The answer to your question is that it really is all player dependent. 

Because the Std. loft of an AP2 4 iron is 24 degrees, most individuals assume a 24 hybrid would be the right replacement. However, some individuals find hybrids with the same loft as the corresponding iron often fly too high. Many individuals get a hybrid that may be a little stronger in loft.

My best advice is to see a local Titleist fitter and hit some different heads and shaft combinations.

If you have any questions, please do not hesitate to contact us.

Take care,

Bubba

Hi my name is Brett, if you liked the loft on the 4Iron, I would definitely get the same loft with your new hybrid. The TM sldr is a great club and so is the titleist 913 h.
