The main reason why I asked the question was that,and I could be wrong on this,is that stand bags do not really fit on to a golf trolley all that well.My brother has a bit of trouble with his.I just thought it would be easier to buy one of these attachments,so when you go to a course and there is no trolleys allowed that day,you can leave the trolley in the car,fit on the bag stand and away you go.Unless we are not using the correct trolley/stand bag.Any thoughts/ideas would be welcome.Plus the fact that I spent ages looking for the right bag and trolley.Does one fit the other?Is there a right combination?
