I use a Nike Performance cart bag because I don't like to carry my clubs and always use my Clic Gear cart. It can be a pain for range sessions but I've gotten over that.
The reason I chose that particular bag is because it was only $120, it has 14 full-length dividers (& a separate putter well), looks awesome and has enough storage for a small army. I truly love my bag and it rides on the Clic incredibly well.
I had a stand bag for a long time but never walked the course. Got a cart bag for more storage and a 15-way divider and have loved it. Always use a riding or walking cart, so don't think I'll ever go back to a stand bag.
Every golf related item I purchase that has no effect on the quality of the shot I am going to hit is picked based on lowest price possible... this includes bags, towels, tools, practice nets, tees, and shirts.... I would much rather buy a 2 year old closeout shirt for 18 bucks than the newest design for 70 bucks...same with shoes.. last years design at half the price is always going to trump a brand new release.
Based on this, for the last 2 years I have been using a Wilson stand bag that I got for 39.99 on sale (retail of 69.99) at Academy sports... I rarely walk, but I prefer a stand bag even though it doesn't fit nice and snug in the carts..I prefer a stand bag because it is smaller which makes storage and getting through the door easier. They are also much more convenient when I go to the range or play on a simulator...even when I am cleaning my clubs.
This current bag is light enough..sure its probably a couple ounces heavier than the superlight high dollar bags but whos going to notice a couple ounces...just remove a couple balls if 2 ounces makes that big a difference to you.
I may replace the thing sometime this year if I find another awesome deal, but as of right now there's no need to. For a cheapo bag it has been plenty durable, all the zippers still work, and the color has barely faded at all. The money I saved on that bag over a new TM or Ogio bag allowed me to regrip my clubs once, maybe twice, and come out even.
Sun Mountain Hybrid - I use it for a few reasons...first off it is non brand specific and therefore I do not feel obligated to have my irons match my bag. This is probably a bad move on my part since it allows me to ho irons!!. Another reason I like it is because it is a larger stand bag, has a ton of pocket space and storage. Not in love with the 14 way divider, but it is what it is. Still keep and sometimes game an older Titleist staff bag....just cannot pull the trigger on a mid-size staff.
Callaway cart bag because I ride most of the time and it will work on my Sun Mountain if I do walk. I also like to be color coordinated so I went with a black/red bag to match the headcovers of my current clubs. 14 way dividers is a must as well as putter tube/well.
