Hello again --the stock systems are fine, just as long as you understand there is only ``so much`` you`ll be able to do with one and if you think you can work it in around the temple area, it will be sent out almost immediately, so you will have it much faster than a custom system. Certainly you can do a bit of experimenting with it, and they are reasonably priced too. The fit most likely will not be perfect though --you can get pleats forming on parts of the perimeter when you adhere it, and that`s purely due to the shape of your individual head compared to a `standard` shape of the stock system. I got one first, while waiting for my custom -- it was fine and as long as you don`t expect too much from it, you should be happy enough with the end- result. Paul.
