The longer the club, the less loft it has....the harder the club is to hit for "mere mortals" or your average every day Joe/Jane. If this were not so, then the majority of the people playing would never have a problem hitting driver. 3woods are generally more forgiving than drivers because they are shorter and have more loft and, these days, because the club head of 3wood is slightly smaller than a VW Beetle on a stick, aka driver.
I used to carry from 1iron all the way to SW and hit everyone of them. I loved the 1iron. Why? Because I could hit it off the tee about 240 yards with 1980s golf balls. But, the 1,2,3 or 4 irons off tight lies in the fairway and out of real rough were just not something that you could bank on getting great results from...at least us mere mortals. So, along comes the more forgiving hybrids. Now, I carry driver, 3wood, 3H,4H then 5 thru LW.
I can still hit a 2 or 3 iron off the deck and have just out screwing around. But the consistency is not the same as hitting the 3H or 4H. My 3wood off the fairway is much longer than my 3iron ever was. BTW, I haven't tried to hit a 1iron off the deck in 10 years. I think I still could but why, no point to it. My 3H and 4H go a little bit longer than my 3I or 4I but are so much easier to hit and I will hit them from the rough.
