What golf club should i get between 3 wood and 4 iron?

If you hit a 4 iron 205 then a 19 degree hybrid would fill the gap perfectly (about 230 yds). I know because I have one and also hit a 4 iron about 200 - 210.

I would definitely say a 7 wood or 5 wood they are pretty easy to hit depending on how you hit woods. If you chose to get a hybrid for sure get an Adams they are superior in making hybrids. If you get woods I would suggest Taylormade burners or Ping G15's or G10's

If you're a slower swinger, go with the wood. The heavier head will help with carry and getting it out of the rough. If you're a faster swing, and possibly good at working the ball, go with the hybrid (Adams, Nickent, Ping, make good clubs... but there are others). Probably an 18-20 degree model. Or, you could have the best of both worlds and go with something like the Taylormade Raylor or Adams A7- something that's got the shorter shaft of the iron (for control) and the bigger head, for forgiveness and rough-plowing.

It depends upon the courses you play and what you hit well. I prefer the 5-wood, personally, but that still leaves me a distance gap (actually two - I use a filler club between my 3-iron and 5-wood). But that's just my preference, because I like woods best and hit my 5-wood as consistently as a comparable hybrid. Given your question, I'm assuming you don't play much and don't take lessons. That being the case, you should stick to a club that's as close to what you already have as possible. The 5-wood isn't a bad club, and you might do well using one that's a mate to your 3-wood. Using a club from the same series allows you to use more consistent mechanics, since it will be similar to the 3-wood in characteristics. However, if you find yourself inconsistent with the 3-wood, you should go try out a few hybrids and find one you like for both fairway and tee shots. Hybrids tend to be more versatile and forgiving.
