Which is better phiten X30 or phiten tornado and why?

Phiten X-30 with Phiten Classic “Star” Custom Tornado Necklace: Design your own Tornado Necklace with these newly released X30 Phiten Necklaces mixed with a Phiten Classic “Star” necklace. As seen on many Major League Ballplayers, Tornado necklaces are comprised of 2 Phiten Titanium Necklaces twisted together into one necklace. The X30 necklace has been processed with 30 TIMES higher concentrations of Titanium than the original necklace for added “power”. The necklace helps relieve pain and stiffness in the shoulders and neck and helps stabilize your whole body. X30 translates into more energy, more power, more speed and less fatigue. Our custom tornados are sewn AND glued for longer life.

Phiten has recently released several new X30 Necklaces: Combat Camouflage (Green/Tan/Black), Digital Camo Night (Black/Gray/White), Digital Camo Woodland (Green/Tan/Black), Denim (demin jeans), Razor Black/Gray/White and Razor Red/Gray/White. You may also choose from one of the Phiten X30 “Tribal” necklace colors. The X30 necklace is twisted with a Phiten Classic “Star” necklace which gives you lots and lots of color choices.
