Wow. 3 iron 240 and driver / 9 iron on par 4's. Sincerely hope your handicap isn't 16.1, if it is what the hell are you doing with your putter?! ;-)
Back on topic, Distances are similar but flight is different. I swapped out my 3/4 iron for a 21 degress 909H and then recently my 5 wood for a 17 degree 909H as the shafts match and the swing feel is very similar so my longer fairway / longer par 3 clubs have a similar look and feel to them. Can pull either out and put the same swing on them. Great flight, easy to hit, easier to hit a consistent shape on them compared to longer irons, and sit down more than the corresponding iron/fairway wood.
