My full bag is a TM Flextech and it is light and well balanced. Pocket layout is good too. I also have a Jones Utility Rover. Good Sunday bag for those that want a couple of smaller pockets for keys/phone etc. Contemplating a waxed canvas Mac but I’m in no rush.
As for wet rounds with a Sunday bag, it’s no big deal. I’m a dew sweeper and haven’t had any issues with wet grips. I just drop the bag down. If you’re concerned about it you could lay a towel down as a buffer between the ground and the bag.
