I know but since he mentioned lag it's kinda pointless to talk about Naia, all the servers are in the same TX datacenter
Depends on where he comes from... If he's from Western Europe he can play almost lag free (read: ALMOST). If from Eastern Europe, I think he'd better go to Innova if lag might be a problem.
But I gotta say, Naia is down again because of the load and lagging badly at peakhours. Not the internet lag, but real server (hardware) lag...
I am from Bulgaria aka the most distant country from servers' location (in EU) and have no lag 90% of the time. Actually my mate at the UK is QQing about lag sometimes and I am experiencing none at that time. It's all about good interenet provider and that's all.
GO BUY INTERNET MENGZ :p
the speed of your internet (so long as it's over 286kbs) is irrelevant, what matters is the quality of your Internet Service Provider's peering. Try battleping (www.battleping.com) there's a half hour free trial, see if it helps. If it does it's your ISP
