I' ve made quite a few custom strings to replace Zebra strings. I measure each string that I take off to determine the amount is has crept. Every one of the Zebra strings I' ve measured has crept substantially, except one that I just recently took off a 3 month old Legacy. Normally, a 3 months old Zebra string that has been shot a fair amount, would have already crept at least 3/8" or more. The one off the Legacy had only moved 1/8" , if it had been right on specs when made. I' m wondering if Zebra has improved their stringmaking recently. The older ones are definitely not well made in regards to their ability to resist creep. This amount of creep on a single cam will cause your bow to go out of tune very quickly.
