Yep, I loved that post, but after two separate incidents of bolts breaking I decided they weren't for me. I weighed about 170 back then and wasn't especially hard on equipment. The Campy bolts had a similar job to do and they were 7mm compared to the Avocet's 5mm. I'd have to say it just wasn't a good idea to use such thin bolts.
Add me to the list of people whose early model 20 computers are still in use, still working fine.
