I also bought the bag boy tri-swivel last year. Its a great cart.
However, I still like carrying, so this year, at least as the season begins, I bought a Sun Mountain 2.5 and I'm going to carry a half set. I bet I score the same.
I am over 50 with a history of doing, as my wife puts it, "$%$%&& stupid" stuff, so my back really doesn't like it when I carry. It's not bad on the course, It's the next day.
