I just got a TPI staff bag. It has plenty of pockets and space for everything I need. It is the best bag I have every owned. Plus it looks great.

Voted for top dividers. As Dr. O said, we all organize our clubs. I started using a cart bag and have had several, but the best was two or three models ago with a slanted top and 15 spaces and a putter well. The slanted top kept the clubs from banging and the 15th space gave me a place for alignment sticks. Also, strong zipper pulls, not the string type as my current bag. Not a fan of snaps for the rain hood. Prefer the velcro straps used on earlier models.

I have been a fan of and would like to see the putter well make a comeback. I liked having that club separate from the others and it also frees up extra space for those other clubs.

BAG COMPOSITE MATERIAL.
I LIVE IN FL AND PLAY YEAR ROUND.
MY TITLEIST BAG USED TO BE BLACK(call it canvas) and it has all faded to 'grey' except where straps protect it from direct sun on the back of the cart.
DISSAPOINTING WHEN OTHERS ASK ABOUT MY TITLEIST BAG AND WHY IT LOOKS SO BAD.

I voted for pockets as I find the current generation of Titleist carry bags have less pocket capacity compared to previous generation carry bags - and given a guess that many carry bags spend a lot of time riding in the back of a cart, having more capacity in the pockets would be helpful!

I voted for pockets but I'd like to see a lot of things in my perfect bag and agree with many of the posts before me. Fair for the lefties to request a bag oriented for them. As a woman I'd like to request a bag oriented for us: the same bags already made but not dumbed down with every shade of pink AND would be 2 inches shorter in total height to accommodate ladies standard length clubs.
My other request would be the internal dividers, those have got to improve across the board. I like the idea from the gentleman who suggested stiff dividers rather than fabric. I have torn mine out since they become useless.

Top divider. It's the primary reason I purchased the Club 14 Cart Bag. My old bag did not have full-length dividers like the Club 14 so the clubs would get all pushed together and make it hard to pull a club and put it back in the bag after a shot. With the Club 14's full-length dividers, problem solved and I love the forward facing pockets, too. All in all, a great design.

Materials because that is such a broad spectrum. As a competitive junior golfer, and traveling around the country for tournaments, materials would be nice to customize, so you don't loos them.

I love the idea a couple folks mentioned about having the ability to switch for a left-handed golfer. That definitely would be unprecedented. Additionally, I would love to see the ball pocket flap have a removable zipper. This would give additional options for customization in case the bag was not custom ordered. How awesome would it be to be able to order a individual flap as opposed to a whole bag. JAT.

I have a 2017 Lightweight Cart Bag and I'd like to see a net material pocket inside the pocket located above the ball pocket. It would give the choice of segregating items in that pocket. I'd also change the side pocket with the magnet on it, as I have no idea what that's usable for. It too small and deep to easily get your hand in there and I would stab myself if I put pencils in their with the point upward.

I would like to customize colors. A distinctive color pattern would help quickly identify my bag when at large outings or tournaments. The current sea of sameness causes everything to blend together.

I voted for straps, because a single strap, properly padded and balanced is still the best. Left/Right heads fore/aft gives you the greatest options and you can alternate how you carry your bag. Double straps never have lived up to the hype.

Need to improve ability to go from carry bag to cart bag in club orginization - front to back for woods. Lowering cuff to accommodate wedges in front. Game changer.

I said straps because I'm 6'5" and I carry. Padding and configuration options would be a bonus!

Pockets. That's what's kept me from upgrading to a new Titleist bag from my 8(?) year old bag. I always carry my bag and need easy access to 1) a pocket for my water bottle and 2) a pocket for my range finder. Unlike all the other pockets, I use these two on every hole (sometimes multiple times). The current bags don't have a drink pocket and the small valuables pocket on the current bags does not provide easy access to the ranger finder. Hope to see these next year!

I went for top dividers. But really I just love the styling of the Staff stand bag. Also used to carry a 14 way divider, the staff stand bag has a 4 way divider only thing I notice is I sometimes pull up an other club. However putting back or taking out clubs is way easier on the 4 way divider than on the 14. So not sure what I would miss really.

No the straps
Only thing I sometime notice is that the straps tangle cross ( the criss cross thing) sometime releases a strap and I have to put it back other than that great product!
