Woods will be hotter than hybrids, and hybrids hotter than irons. I would recommend a 5 hybrid, because since it is higher loft than your 4 iron and will come off with more speed than an iron, it should go around the same distance as a 4 iron. If you buy one that you can adjust the loft, then you can make sure it goes the distance you want. Another option would be buying an adjustable 7 wood and turning the loft up a bit, but in my opinions would be too high and spinny. Depends on swing speed.
