My advice is not to sell either unless you are over 60, in which case you may wish to sell the 3-wood. Keep them both as you will grow into them. You'll probably be able to hit the 5w in 6 months and the 3w in a couple of years. Likewise, you'll be able to hit the 4-iron (unless you are a senior). A 5-wood is a replacement for a 2-iron, and a 7w and 3h are about the same in distance. A hybrid is a very useful club for several reasons: its trajectory is lower than a comparable wood, and this can be handy. It is very good out of the rough. However, hybrids can also be difficult to hit, especially the lower ones. I found a 4-hybrid much easier to hit than a 3h when I was just starting. Persevere and ability to hit all these clubes will come.
