I'm trying to figure out where the hole is. I'd be tempted to carry a three or four iron, not necessarily to hit full shots with, but for punches from under trees, or even longish chips. (I'm inclined to chip from near the green where some would putt. I think flying over the stuff that's not the green, but then getting the ball rolling, is better than chancing getting stuck.) The other option would be a 60 degree wedge, maybe never to hit a full shot with (I think that's a bear) but for hopping over bunkers when there's no green to work with.
When I'm hitting right, I find my gaps are more like 12-15 yards, and my 8 goes 140-145, but we are pretty similar.
