re: the disk drive. they're really pretty terrible wheels. yeh they're the best sounding wheels ever made, I used to have a pro clear 1 with a older hugi & u could hear it coming a mile away. sounded like a motorbike! unfortunately the wheel flexes a lot, weighs a lot, heavily affected by sidewinds, any nicks in the kevlar cord & the wheel looses its tension & eventually gives up. obviously any big rock impact could kill it straight away. If you want 1 save it for retro posing only! they go for around £100 on ebay
