The JT Proteous is to tight if you like freedom,
The Nuvis is just as tight, but smaller,
The Dye Invision yet again Tight to your face, bit looks good and is comfertable,
The JT Spectra is the best out the lot, (in my opinion) its comfortable, not attached to your face!! and you can now get the JT Pro Flex's just the same, but even softer!!
Your choice mate, but JT Pro Flex anyday!!
