I have one of Luke Donalds tour bags which i carry round courses, the balance on the shoulder is perfect even fully loaded, cant wait until the new one comes out in september 2009.
Have the new 2009 /2010 bag
Have the new 2010 Stand Bag
Have the new 2011/2012 Luke Donald RBC Bag
Change my clubs from the Mizuno T3 to the new JPX 800 in september 2011 via a mizuno custom fit center. The new clubs with steel shafts added an extra 20-30 yards on each club distance so well worth the change from graphite to steel.
As Mizuno keep updating there clubs i have found out i can't get the 3 extra ones in the set which are the gap wedges with the same jpx heads so i have stayed with my old T3's to make up the set.
The new 2012 bag is smaller than normal only being 9.5 inch but has some nice features like a waterproof pocket, remove the front flap, fits in the boot of the car, you can still fill it up with all the items you need but i do find the clubs dont have much room but hey when you get a Luke Donald Mizuno bag you have no reason to complain.
