Just received the Stadium from Callaway's customer service to replace my Org 14 Weekender cart bag (broken shoulder strap).
Let me say the experience with Callaway's customer service far far exceeded my expectations. I called on a Thursday and I received the following Monday. As they had no shoulder straps to send, they shipped me a new bag. They even gave me a few choices. The best part was -- No charge, No hassles, No questions asked, and a very courteous, well informed, and well spoken representative. She made my day.
NOW TO THE BAG...
The Stadium is very much configured like the Weekender. It has one less front pouch but two of them are larger then the Weekender. Side pouches are identical to the Weekender (Long and spacious with one side insulated with drainage for melting ice). So I'd have to give the nod to the Stadium
The Stadium shoulder strap doesn't have as much padding as the Weekender's but no one is going to carry for a round. Given my Weekender 's strap broke and I have no mileage with the Stadium, we'll call this a push.
The one change I like over the Weekender is the large hand grasp just below the front pouch. The weekender has one but difficult to locate and grab. It makes it easier to lift into the trunk of the car. Nod goes to the Stadium.
They both have the same number of full length sleeves (14) plus (1) external putter well. However the Stadium has a few sleeves which are wider. No big whoop but sometimes I throw a few extra clubs in the bag when heading to the range. So the extra space is appreciated. Slight nod to the Stadium.
The only con I could include is the external putter well placement. It gets in the way of the lower strap of my push cart. Fortunately the bag is well balanced on the cart and just the top strap suffices. As they both have the same configuration, we'll call this a push.
As I looked at a lot of cart bags on my last purchase, the Weekender or now this year's model, the Stadium, stood out over the rest. Plenty of compartments, compartment sizes, full length sleeves, an insulated beverage pouch big enough to carry a six pack (if you so choose) and roughly the same weight as many stand bags (less the six pack of course). Plus the price was cheaper then many of the other full feature bags.
I hope this helps. Happy hunting!
