Bags tip. Living in New England playing hilly and mountain courses it happens. My GRIP tips from time to time. My buddies ERGO tips from time to time. I don't think it should be a deciding factor in a bag purchase.
However, with the ERGO having the vertical disc carry, it is easily the lightest bag on the market. Big Hyzer could put a small counter weight in the bottom of the bag to keep it upright. The bag is so well designed it would still feel like you are carrying nothing.
I want an ERGO for the sake of my back. I generally play between 7-10 rounds a week. Sometimes on weekends I play 54 or 72 a day. This bag could be a life saver. Any unhappy ERGO customers want to trade straight up for a two week old GRIP??
