Although I can hit it longer sometimes, my averages are as follows:
D: 265 (10dg)
3w: 240 (15 dg)
2h: 215 ish (18 dg)
3i: 205
4i: 195
5i: 185
6i: 175
7i: 160
8i: 150
9i: 135
PW: 120
Of course, these distances can vary wildly depending on conditions. I had the luck of playing the Prince Course on Kauai last week during a vacation and you could throw those distances out the window. On the first hole, which was downhill and downwind, I smoked a 3 wood 280. On the finishing hole (about 410 yds), which was uphill and against the wind, I hit a good drive about 220. BTW, I don't know if anyone else has ever played the Prince, but it is EASILY the most difficult track I've ever played. At the end of the round, the pro told me the course record from the tips was only 68!?!?!
