We find that a lot of customers just need a little advice and then they're ready to tackle bladder issues themselves.  Here is one example of a kite owner that needed a little help working up the courage to address an issue in a SPRINT system.

thank you for the advise. I unzipped pulled it out and found a semi circle slit in the bladder the size of a dime. I bet I received it from the factory in this condition, as my other kite bladder repairs were always small holes. Either way I patched, it seemed to hold tight, thank you for the advice as I was hesitant to fool around with it considering it was a sprint system. Todd
