I can't hit woods for toffee. I'll take a long iron any day of the week for this reason. However as I'm using an original set of Titleist DCI golds I'll go a bit more and use the 3.

And that’s why there are choices..

Curious what the loft is for the DCI 3 iron versus the modern 4 irons. The number on the bottom is as useful as shaft flex.

5W & 7W all the way. This bag is old faves down to the 7 iron. The 34H is "course conditions".

Don, the lofts on the DCI irons were 21* in the early 90's, 22* in the late 90's amd 21.5 in early 2000. The modern 4 iron in Titleist T series have lowest loft at 20* in the T350 and the highest in the T100 at 23*. The current T350 four iron is stronger than the earliest DCI 3 iron.

I find that Titleist woods and hybrids are much easier to control. Seven iron my longest iron. I have a TSR1h 20* and GT3h 23* in my bag. The rest is a GT2D 10.75*, GT2F 14.25*, TSR1F 17*. At 79 this really works well for my game. Something my fitter figured out. Mitsubishi Tensei K Blue Regular Shafts. If you work with the right fitter you will get the right results. Just saying.

I absolutely love my 5 woodTS2. Automatic 200 yard club.

A 5W is not a 4 iron replacement, unless you're replacing P7shovels. A 5W would replace the distance of a 3 iron, or 20° hybrid.
A 4 iron replacement would be a 7W/9W at around 23° or a similar lofted Hybrid.

I play GT3 5 wood at 18 Degrees and carry a U505 3I one degree weak (20 to 21). If I have a tail wind behind me I go 5 wood since I am a longer hitter (5w 245-260 carry) unless there is a downward slope or it is a hard fairway/firm and a longer hole where distance is key. I am long with my driver but can lose it so it's not worth it on some courses/holes. Any danger past 260 I hit 3 iron since that carry is 225-240-ish plus good roll out. When the wind is at me or sideway, I go U505 3I and it stays below the tree line and some distance is made up by roll out. This is all off of the tee where I am more concerned with having plenty of weapons to get off the the best I can. So for me that is carrying the big stick when it's open, 5 wood and driving 3iron (U505).

I do not carry a 3wood and I play 5 wedges (T200 PW & 48 and Vokey 52, 56, 60)... I mention this because I do find myself at times in the 215-230 range without a comfortable choice both off the fairway/rough or tee (I am not the best at hitting the U505 off the deck unless it is purred) and the 5 wood is to much for that gap. I am considering a 4 hybrid turned down a degree to lock in 215 to 230 and swap that out for the driving 3iron on non-windy days since the 4H will go a little higher.

I want height when the conditions aid itself to it and I want lower flight w roll out in the wind. So for me I make these choices based of weather and course conditions. Similar to swapping out a high bounce SW for low to medium bounce based on conditions.

Have a great one!

I'd be more concerned with ball contact than with ball flight or roll out.I would take both to the range and which ever one you make better contact with, put it in the bag.
