I agree. If traffic is high value or high volume, it is worth setting up redirections etc.
For low value or volume traffic, it probably isn't.
Even then, I moved about 20-25% of my domains back to trafficz as they were actually earning more there than at domainsponsor.
My best domain at domainsponsor is earning about US$13 per month at domainsponsor now compared to US$2 a month at trafficz which is nice
