Miami Sony Ericsson - any tips?

[nyc]

Looking to get tix for this year's Miami SE. Does anyone have any insights/tips on what tix to get and what day would be great?

I've been going to the US Open for the last few years and kinda figured out what works best to view the action up close and personal.

At the US Open I usually end up getting tix for the Armstrong, as you can't see anything at Ashe anyways and I love being in a more intimate setting like Armstrong or Grandstand, and like to cruise around the outer courts anyways. Occasionally I've been to the practice session on Sunday before it starts as well.

I have one day I can plan for in Miami - do you recommend a particular day and tickets to get and where to get them? Should I do Main Stadium or Grandstand? I was initially thinking 2nd Round as there's plenty of action on outer courts. The SE site has lots of tickets listed as sold out, but some other websites have them listed as available but seem to get you with "service charges"

Appreciate any insights and help!
