I always end up referring back to the web when I do a cron job because once I do them I rarely ever have to go back. I end up forgetting the order of the fields and yes I do us ally use the 5 fields instead of the @something because of compatibility problems. The only @something I use on any sort of regular basis is the the @reboot as an easy way to start something as a non-root user that doesn't warrant its own start up script. I hope this helps.
