Skunk2 vs Crower Ti Retainers.....

I was just wondering if you think they are basically the same or not. They are both good name brand titanium retainers, do you think they are the same in strength and performance? What if i mixed them together like Skunk2 dual valve springs and Crower retainers.... do you think it'll cause any potential problems in the future?

i personally have the crower ti, but im sure they arent much better/different than the skunk2's. they are prolly different amounts of actual ti, and other alloys mixed, but as far as getting skunk2 springs, and crower retainers, it shouldnt be a problem.
