stupid question about starting 6max

[iluzion]

I'm sorry if this has been posted a lot, I searched and read through a few pages here looking to see if I could find any discussion on the topic, but I failed.

I'm a 3/6 player whos only put in a few thousand hands there, and the addition of the 6max tables is making me want to start on 6max now rather than waiting for 5/10, but am unsure where to start. Should I start trying to learn 6max down at the 1/2 tables or go ahead and take the risk at 3/6?
Or even what about depositing some money on another site and playing 6max anywhere lower than 3/6?
