I inspected my platytpus 2day and apart from a tiny hole which can be repaired by putting a patch on it I also saw white cracks in the plastic. Should I be worried? And I saw the first layer of plastic is coming lose at parts, is this worrying too? Is it time to buy a new one? And if it is time to move on what should I buy? I know camelback is good but which model? If i have to, I dont mind investing money but I dont want to end up with something wrong. HELP<br>thanx reinhardt
