Well, I picked the "other" category because there was no "Sand Wedge." I love that club and use it for everything I can. So for me, 3-Wood, 5 iron, 8 iron, sand wedge and putter!
3-wood - Good distance off the tee, easy to use off the deck and can be used for chipping, it's versatile!
5 iron - this is the best club in my bag, I hit it the same distance every time on full shots, and have a good feel for it when trying to draw, fade, etc. I love this club, from 120 and out it's my "go to" club.
8 iron - from 120 and in, it's my "go to" club! Makes a nice pairing with the 5 iron.
Sand Wedge - 56/10, reacts lovely to Michigan ground. This is the best wedge in my bag, and it flys high and actually stops when it lands on the green (I suck at trying to spin the ball, so when the ball stops, I love it).
Putter - Though I hardly need this club, I suppose it would be good to carry for those rare incidents when I don't hole out from the fairway or tee.
