Hybrids

I bought a 913h 19 degree to replace my 3 iron. What degree should I buy to replace my 4 iron?

21 or 23 i would think

24for the 4 iron

I would suggest going to a certified Titleist fitter and try to determine your need for that club (distance, flight, spin,etc.  The fitter can get you into the right club for your game.

I would check the gap in distance between the 19* hybrid and your 5 iron.  You'll need whatever degree to fill that gap.  Probably wouldn't hurt to see a fitter (like TT mentions), if you need help.

you need to first figure out your gaps because they are different for everyone.  I use a 21deg 910h as a 3 iron replacement.  I hit my 4 iron (AP1's) 195yd and the 21deg 910h (my 3 iron) 210yd.  I have a friend that has the same irons (AP1's) yet he goes from his AP1 4 iron(185yd) to a 19deg 910h (200yd) an has the same gap.

15 yards btwn a 21h and 4 iron is about avg given hybrid generally get 5 more yd than same iron. The friend may hit a 21h and 3 iron same.
