mrjoehohn has a valid point at [4] --there are /would be issues around changing one system for another, in more `` messing`` about with clean -ups etc. and time -consumption..... interesting that you find no appreciable difference it terms of how your all -lace systems cope with your active lifestyle ..... as opposed to the likes if the `special`exercise base. I reckon that it can, again, be down to an individual`s body -chemistry and also how much physical exercise you do, along with frequency of showers, that will govern how long a particular bond will last, but there is no need to worry unduly as a new wearer, that, on your first day ,after your first workout and shower, that the system will part company with your scalp !! LOL. As for the life span of a system which is exposed to a very active lifestyle, I would think that is will surely shorten it to an extent, which is perfectly understandable, but overall, should not put anyone off wearing..... just means you`d have to order a bit more frequently. In utah23`s case ,he is more worried about the bond becoming weak and the system lifting at the front....... I`d order a few glues/ tapes with varying strengths and see how he gets on with them -- it`s a matter of experimenting at first to see what will work best for him, but he can be assured that he`ll be able to wear with confidence. Best wishes... Paul.
