Best club to replace my 4iron with?

Yea I suppose the answer is to go and test them out and see. I was just hoping someone would come in here with the magic answer

U505 3-iron

I have a 1 and 3 irons in those. Ball really jumps off the clubface

My 7w is my favorite club in my bag.. I also hate hitting hybrids.. I don't know what it is, I carried a hybrid for years and just never hit it well.. when I found the 7w I will never go back..

That said , I also carry a 4 iron.. similar in distance but the 4iron has a different ball flight.. lower more piercing..

I built a 9 wood year ago and threw it in the bag. It’s the only club that never changes. It’s so easy to hit and lands soft. 215-230 depending on fairway vs. tee

Try out a 5 hybrid. I have a 24° TSR2 hybrid that fits the bill perfectly. It's my 210 club. Even if it seems like it would be duplicative with the loft of your next iron, the longer shaft length gives it more carry than the loft would indicate.

For non tournament rounds I keep 15 clubs in my bag and go Driver, 3W, 3H, 4H, 4I.

My 3 hybrid is an absolute rocket launcher (my favorite club in my bag) so there's a pretty big gap in distance between my 3H and 4I when I'm playing in tournaments. But I found the 4H adjusted to a higher loft is a really good 3I replacement. Gets a higher trajectory, lands softer, more forgiving, and loft can be adjusted. Even if I was trying to replace my 4I like you instead of my 3I, I would still go with a 4H or 5H. I've for some reason just never hit a 5W or 7W too well and have loved the hybrid ever since I put one in my bag years ago so it's an easy choice for me.

If you can get fitted on a trackman i would go do that. My 4h is my 200 club with almost no rollout (which is exactly what i wanted it to be). But there was tremendous difference between various hybrids and similarly lofted woods. Ultimately settled on TSR2, and it is my most reliable club now. Had never owned a Titleist club and definitely wouldn't have picked it without fitting.
