I have been reading that wearing a strap on your speedy can tear the handles and SA's advise against wearing it. This doesn't seem logical to me. It doubles the stress on the straps, so double the weight. I haven't heard people tell the strap toar away wearing the bag without the strap and much in it. If the neverfull can hold alot of weight the speedy should aswell. What do you think, is i a way of Vuitton to stop you from adding something to a design just like they refuse to sell luggage tags if you don't have a keepall?
