I joined a local golf simulator. 20 something HD versions of famous courses, plus a fully stocked bar and food. Not the same as being out on the grass but it's warm and close by! It was great to hit the ground running last spring.
Trial and error for me as well. I started by figuring out what my most comfortable and accurate approach shot was. When I'm on the tee I start with that and work backwards to figure out what I need to do to get me there while avoiding any trouble. Quite often this means leaving the driver in the bag even though it's a par4 or par5.
I also almost always go for the center of the green rather than taking dead aim at the flag stick.
My father's Pro had what I think is...
Most likely you were able to connect closer to the sweet spot more often with the heavier head. With a lighter swingweight some people can have issues delivering the clubhead to the ball accurately - I think basically the brain has trouble perceiving where the club head is. I find I can't hit my driver well without a swingweight of at least D0. Some people like it around C5 (very light), some people like it really heavy like a wedge (my brother likes D6 for his...
I carry 95% of the time. I usually only use my push cart if it's going to rain (umbrella holder). I find carrying much less work than pushing or pulling; it's less effort to simply walk with something on my back rather than actively pushing or pulling something. I know on really hilly courses I will always carry regardless of weather.

Had a rough round today, didn't hit many greens. Really windy with gusts up to 45KM/h at times. It was really bad on the front 9 where I shot +11. The wind died down a bit and I was +3 on the back 9 which was actually better than my previous round at this course.

Played a fun and challenging (very hilly, lots of hazards) executive course today. My parents are members so with the long weekend early twilight and members discount it's a great deal. I had 4 bogeys and 2 birdies, each split evenly per side. Nice and consistent and my putting was excellent today. Going to find something longer tomorrow, but the executives sure do give you a great idea of where your iron game is.
I carry a 17deg 4W that I rarely use (I don't carry a 3W). I carry 230yd with my 7W and 275yd with my driver and rarely seem to find myself in need of the 250yd shot of the 4W. It probably has to do a lot with the courses I play though. I remember on my trip to Florida I pulled it out a lot more, long holes with huge fairways aren't the norm around here.
