Re: best cart bag?Sun Mountain C-130 is what I have (the '07 model) and it is great, although not perfect. As long as you don't anticipate having to carry it to far I would go for it, but if you might have to do a fair bit of walking to/from clubhouse or whatever, then it may not the be the best option.
There was an excellent discussion on cart bags you should read in this thread:
Here is what I had to say about the C-130 in that thread:
I use it about 80% of the time on a pull cart, and 20% on a power cart.
The only cons of this bag are the sheer size and weight. If you have much of anything in the side pockets, it can take up more than its share of space on a power cart... It would be hard to put two of these suckers side by side I think. It barely fits in my trunk. It also is pretty darn heavy and a bit akward when you have to carry it (such as going to the range, especially when the main level is full and you have to take it upstairs!). It does have an extra wide padded shoulder strap, but the balance isn't quite right on it, and it tends to want to slip off your shoulder while walking.
