I have a dual strap bag, but a push cart. I carry it as a single strap until I load it onto the cart... I'm old... gimmie a break...lol
Sunday bags usually don't have the weight to fully need a dual strap though I'd think...

All bags should have double straps.

On my regular carry bag I use a double strap, but for a Sunday bag with fewer clubs I think the single strap is sufficient.

I love my single strap. I will play a quick round late on a Sunday afternoon. I carry 5 clubs, a sleeve of balls, and a bottle of water.

I prefer the versatility of the double strap, options for comfort.

Like the double strap also, with the additional Titleist logo.

I have a Titileist bag with a double strap. I had a push cart for one year. It bothered my legs and back more than carrying so I bought a new bag. I need to come up with a new reason to buy a new Titileist bag!

Single for me

Double strap and better better on the old back and shoulders. If adjusted correctly, like carrying almost nothing. =)

I agree, Sunday bag shouldn't be too heavy, so one strap would be fine by me.

Double strap for me

even though I usually only use the one strap, I like having the option of 2 for long walks to the car and clubhouse etc.

Single. I use my Sunday bag for range work and/or running out to play a few holes with 5 or 6 clubs. Light load so I don't expect help with weight distribution. The extra strap just seems to get in the way.

Single Strap. It's difficult to swap shoulders with a double strap bag, yet quite easy to do with a single strap one. A Sunday bag should be a smaller load with a lighter overall weight.

Double strap, easier on the back even if it is a Sunday bag

I used to be a single strap guy but have converted to a double guy

Duel strap

Sunday bag, single strap more than enough!

I have this bag and use it for winter play (note I also use my DCI's, 909 woods, and dead center putter during winter, AP's and Scotty catch a break). It is perfect as is with 1 strap. With the extra clothes you can easily move it from shoulder to shoulder. With the "legs" it keeps heads off wet surfaces. Lastly you carry limited clubs (I average 8-10 with this bag) so it is easy to carry.
