Hello, I am about to pull the trigger and get either a Mizuno Renegade, Aerolite III, or Twister III stand bag. The problem I have is I can't try it out in store first and I've never seen a golf store near my location that carries the Mizuno brand. Can anyone elaborate more on the shoulder strap system they use? I can't find a good picture even through fleabay of the most recent models.

The item description lists it as using the IZZO system, which has me worried because Callaway bag's say the same thing. I've tried using the Warbird before but there is a plastic clip right by the handle on the bag that really digs into my back when I am trying to carry it. Perhaps I don't have it aligned right, but it is the only style I really can't stand. I think that the Mizuno uses a 3-point system similar to the ogio where there are 2 buckles on top of bag and one below near the cooler pocket, but I really can't tell.

So, if anyone has any extra info I could use to make this decision please help a guy out.
