Don't equate Octalink with ISIS. I have two bikes with Octalink bbs (one a 5500, 105 level and the other a 6500 Ultegra) and both have been extremely durable. The 6500 has over 36,000 miles and is still in fine condition. The 5500 is still relatively new with only about 6,000 miles and operates like new.
ISIS was a public domain design and they were made by numerous manufacturers in a huge range of prices and quality. The poor ones were very bad and gave the whole design a bad name.
