I tried looking up TEC Chaos and didn't find anything. The Columbia 300 Chaos' that I did find all appear to be particle balls. The only companies that I found that still make particle cover stocks are Lane 1, RotoGrip, Storm, and Lord Field.
You might be better off telling us how your old ball used to react, what lane condition you would normally be playing on, and maybe a little bit about your style ( speed, rotation, rev rate, etc.)
